Answer:1) Parse-by-value
2) Parse-by-reference
3) Parse-by-name
Explanation: Parameter parsing refers to a communication among procedures or functions.
The values of a variable procedure are transferred to the called procedure by some mechanisms. Different techniques of parameter-parsing include; parse-by-value, parse-by-reference, parse-by-copy restore, parse-by-name.
Can you please at least give me some part of the code. At least how to start it in C++. Thank you!
Project 5: You will design and implement various classes and write a program to manage one of the following a bank, a hospital, a library, a business, an organization, etc.) The program must do the following:
1. Allow the initialization of the different attributes of the objects from the keyboard.
2. Allow the initialization of the different attributes from a file
3. Perform calculations on one (or more) of the attributes (e.g. calculateInterest, generateHospitalBill, calculateCheckedBooks, etc.)
4. Output a report of all objects created. The report called for by requirement 4 should output all information about each object. You will need to take advantage of the capabilities of C++ classes, inheritance and overriding.
Program Design:
1. Create at least one base class. All data members have to be private. Your main function and any function that it calls should use the member functions of this class for all transactions.
2. Create at least two derived class of the base class described in the previous point.
3. The program will maintain arrays of objects that interacts with each other to manage the designated establishment (bank, hospital, library, etc.). Please do not use anything more sophisticated than an array.
4. Keep the program simple. I am interested in whether you can demonstrate basic competence in the use of classes, inheritance, and good design.
5. All data members in the classes must be private. This is to assure that you use the C++ capabilities that this assignment is all about. Do not use any global variables.
6. When the user decides to quit the updated information is saved back to the secondary storage to give the user the option to either start fresh or continue where he/she left off at the beginning of the next execution

Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substring() method to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990.
Ex: If the input is:
March 1, 1990
April 2 1995
7/15/20
December 13, 2003
-1
then the output is:
3/1/1990
12/13/2003
Given Code:
import java.util.Scanner;
public class DateParser {
public static int getMonthAsInt(String monthString) {
int monthInt;
// Java switch/case statement
switch (monthString) {
case "January":
monthInt = 01;
break;
case "February":
monthInt = 02;
break;
case "March":

public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
// TODO: Read dates from input, parse the dates to find the one
// in the correct format, and output in mm/dd/yyyy format
}
}
Using the knowledge in computational language in C++ it is possible to write a code that complete main() to read dates from input, one date per line
Writting the code:#include <iostream>

//else try to process the input
try
{
//find and extract the month name and parse it to monthInt
monthInt=DateParser(input.substr(0,input.find(' ')));
//find and extract the day and parse it to dayInt

I need the answer to the below question *ASAP*
2 4 9
Explanation:
Basically what I thought was the way was, since 2 is first, then its 1, then since 4 is second, it's added second, lastly to get the last oneI added them all and got 9 so that's third.
Answer:
Does not exist.
Explanation:
The answer is not in the option:
Let's analyse the code:
random.randint(2,4)
This means take in random integer numbers starting with 2 and ending with 4.
Meaning numbers : 2, 3 and 4
Next math.pow(a,2) means a× a = a2
So when we input 2 the function;
math.pow(a,2) returns an integer 4
You do same for input 3 , it returns 9.
For input 4 it returns 16.
And the result is encapsulated in the function string(). Meaning display the result as a string:
4 9 16

A(n) ________ is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.
Answer:
Network Operating System (NOS)
Explanation:
A network operating system (NOS) is an operating system that makes different computer devices connect to a common network in order to communicate and share resources with each other using a server. A network operating system can be used by printers, computers, file sever among others, and they are connected together using a local area network. This local area network which they are connected to works as the server.
The NOS also acts as a network security because it could be used as an access control or even user authentication.
There are two types of NOS
1) Peer to peer network operating system.
2) Client/server network operating system
A network operating system (NOS) is a server-based operating system oriented to computer networking and may include directory services, network management, network monitoring, network policies, user group management, network security, and other network-related functions.

The beginning of a free space bitmap looks like this after the disk partition is first formatted: 1000 0000 0000 0000 0000 0000 0000 0000 (the first block is used by the root directory). The system always searches for free blocks starting at the lowest numbered block, so after writing file A, which uses 8 blocks, the bitmap looks like this 1111 1111 1000 0000 0000 0000 0000 0000. Show the bitmap after each of the following actions: (a) File B is written, using 12 blocks (b) File C is written, using 7 blocks (c) File A is deleted (d) File B is deleted (e) File D is written, using 6 blocks (f) File E is written, using 9 blocks Show all steps.
The bitmap is 1110 0000 0001 0000 after some use. The system always looks for free blocks beginning using a contiguous allocation technique.
What is a bitmap?After some use, the new bitmap is 1110 0000 0001 0000. The system employs a contiguous allocation mechanism and starts searching for free blocks at the position.
(a) File B is made up of five blocks, 1111 1111 1111 0000.
b) The batch number 1000 0001 1111 0000 deletes File A.
c) Eight blocks are used for writing in file C.
1111 1111 1111 1100
File B is deleted (d). 1111 1110 0000 1100
Free-space bitmaps are one method used by some file systems to keep track of allocated sectors. Even though the most fundamental implementation of free-space bitmaps is incredibly wasteful, some modern file systems use complex or hybrid versions of them.
Therefore, after some use, the bitmap is 1110 0000 0001 0000. The contiguous allocation strategy is always used by the system to look for free blocks to start with.

When implementing a physical database from a logical data model, you must consider database performance by allowing data in the database to be accessed more rapidly. In order to increase data availability, the DBA may break up data that are accessed together to be stored together. Which method will improve the performance of this structure when running queries? What are advantages and disadvantages of this method?
Answer:
A method used to improve the performance of structure when running queries is known as Partitioning indexes.
The advantages of partitioning indexes are, It enables data management operations for example, index creation and rebuilding, It increases query performance.
The disadvantages are, one cannot define the primary index of partitioned table to be unique unless the whole partitioning column set is part of the primary index definition.
Explanation:
Solution
Partitioning indexes are known as b -tress indexes that shows hon how to break up the index into separate or different partitions.
Partitioning is usually done to enhance the performance and increased availability. when data are spread over multiple partitions, one can be able to operate on one partition without affecting others. i.e to run utilities, or to take data offline.
Almost all DBMS products support partitioning, but in various ways. we must be sure to know the nuances of an individual a particular DBMS execution before partitioning.
The advantages of Partitioned indexes are as follows:
It enables data management operations for example, index creation and rebuilding
It increases performance of query
It can significantly the impact of schedule downtime for maintenance operations
Disadvantages:
The primary index of partitioned table cannot be described to be unique except if the whole partitioning column set is part of the primary index definition.

if the number of texts is less than or equal to 60
Extra Charge=0;
If the number of texts is greater than 60 and less than 200
number of texts b/w 60 and 200 =number of texts-60;
Extra Charge=0.1*(number of texts b/w 60 and 200);
else If the number of texts is greater than 200
number of texts beyond 200 =number of texts-200;
Extra Charge=0.25*(number of texts beyond 200)+0.1*(200-60);
Display Customer Name
Total Bill=Basic bill+Extra Charge;
Total Bill after Tax=Total Bill*1.12;
1. Implement the function dict_intersect, which takes two dictionaries as parameters d1 and d2, and returns a new dictionary which contains only those keys which appear in both d1 and d2, whose values are a tuple of the corresponding values from d1 and d2.
E.g., dict_intersect({'a': 'apple', 'b': 'banana'}, {'b': 'bee', 'c': 'cat'}) should return {'b': ('banana', 'bee')}
2. Implement the function consolidate, which accepts zero or more sequences in the star parameter seqs, and returns a dictionary whose keys consist of values found in those sequences, which in turn map to numbers indicating how many times each value appears across all the sequences.
E.g., consolidate([1,2,3], [1,1,1], [2,4], [1]) should return the dictionary {1: 5, 2: 2, 3: 1, 4: 1}.
Answer:

The following if statement uses an overloaded > operator to determine whether the price of a Car object is more than $5000. Car is a struct and myCar is an object of Car. Each Cor object has two variables: id (int) and price (float). As you can see in the following code, the ID of myCar is 12345 and the price is $6,000. Car myCar - [12345, 6000.); float price - 5000; if (myCar > price) cout << "My car price is more than $5,000/n": Which one of the following function prototypes is correct syntax to overload the > operator based on the if statement above. void operator> float price: O bool operator>(Car & car, float price): bool operator (float amt): bool operator> Car & your Car): None of the above
Answer:
The correct syntax to overload is bool operator (float amt): so, the third statement is right.
Explanation:
Solution
From the given question we have to find which statements is correct for the following function prototype.
Now,
Since the price of a Car object is above $5000, the car here is considered a struct and myCar is an object of Car
Both Car object consists of two variables which are id (int) and price (float)
Thus, from the given example the corresponding code says that the ID of myCar is represented as follows:
myCar - [12345, 6000);
The float price = 5000
Then,
cout << "My car price is more than $5,000/n"
Therefore the following statement bool operator (float amt): is the right syntax to overload.
Given: The following if statement uses an overloaded > operator to determine whether the price of a Car object is more than $5000. Car is a struct and myCar is an object of Car. Each Car object has two variables: id (int) and price (float). As you can see in the following code, the ID of myCar is 12345 and the price is $6,000.
Car myCar = {12345, 6000.};
float price = 5000;
if (myCar > price)
cout << "My car price is more than $5,000.\n";
Which one of the following function prototypes is correct syntax to overload the > operator based on the if statement above.
a. void operator>(float price);
b. bool operator>(Car& car, float price);
c. bool operator >(float amt);
d. bool operator>(Car& yourCar);
e. none of the above
Answer:
Option(c) is the correct answer to the given question.
Explanation:
In the given question car is the structure and mycar is the instance or the object of the class also the object mycar holds two variables of type integer and the one float variable .
Following are the syntax of operator overload in C++ programming language
return -type operator operator-symbol(datatype variable name )Now according to the question the option(c) follows the correct syntax of operator overload
All the other option do not follow the correct prototype that's why these are incorrect option .

Write a C++ program to find if a given array of integers is sorted in a descending order. The program should print "SORTED" if the array is sorted in a descending order and "UNSORTED" otherwise. Keep in mind that the program should print "SORTED" or "UNSORTED" only once.
Answer:
The cpp program for the given scenario is as follows.
#include <iostream>
#include <iterator>
using namespace std;
int main()
{
//boolean variable declared and initialized
bool sorted=true;
//integer array declared and initialized
int arr[] = {1, 2, 3, 4, 5};
//integer variables declared and initialized to length of the array, arr
int len = std::end(arr) - std::begin(arr);
//array tested for being sorted
for(int idx=0; idx<len-1; idx++)
{
if(arr[idx] < arr[idx+1])
{
sorted=false;
break;
}
}
//message displayed
if(sorted == false)
cout<< "UNSORTED" <<endl;
else
cout<< "UNSORTED" <<endl;
return 0;
}
OUTPUT
UNSORTED
Explanation:
1. An integer array, arr, is declared and initialized as shown.
int arr[] = {1, 2, 3, 4, 5};
2. An integer variable, len, is declared and initialized to the size of the array created above.
int len = std::end(arr) - std::begin(arr);
3. A Boolean variable, sorted, is declared and initialized to true.
bool sorted=true;
4. All the variables and array are declared inside main().
5. Inside for loop, the array, arr, is tested for being sorted or unsorted. The for loop executes over an integer variable, idx, which ranges from 0 till the length of the array, arr.
6. The array is assumed to be sorted if all the elements of the array are in descending order.
7. If the elements of the array are in ascending order, the Boolean variable, sorted, is assigned the value false and for loop is exited using break keyword. The testing is done using if statement.
8. Based on the value of the Boolean variable, sorted, a message is displayed to the user.
9. The program can be tested for any size of the array and for any order of the elements, ascending or descending. The program can also be tested for array of other numeric data type including float and double.
10. All the code is written inside the main().
11. The length of the array is found using begin() and end() methods as shown previously. For this, the iterator header file is included in the program.

b. This acquisition happens very quickly and on day one the business needs people at Uni-Tech to connect to hosts at Acme using hosts names that can be resolved by Active Directory. Describe a method for integrating the two environments that does not require too many individual tasks that will take many hours. (10) Describe how you would test to make sure your integration is working correctly.
Answer: Provided in the explanation section
Explanation:
(a). BIND is a type of DNS server used on the internet, actually it is reported to be most widely used DNS server on the internet. Also BIND is the de-facto standard on Unix like operating systems and Linux. Thus it can be used to locate computers on a network using domain names instead of their IP addresses. BIND was originally programmed at the University of California, Berkeley in the 1980s, this was made possible by a grant from US based DARPA program.
Originally, BIND stood for Berkeley Internet name daemon, but nowadays it is called Berkeley Internet name domain.
(b). In some of the clients in windows and Windows servers we will install LDP. By the LDP.exe we can test tDNS, Active directory woking , even we can add or modify. LDP is used to test and verify the Active Directory objects. We will install in windows machine then open the software, then from the menu we will select connect and type the IP adress of the Active Directory then we will select or type the objects of Active directory. For Linux system we have to openldap and can search the AD.
From Linux or Unix we can use the nmap tool which can test the network connectivity between all the computers whether it is windows or Linux. By nmap we can test by ICMP protocol to verify the network connectivity. By nmap we can scan all the port which are required to open from client to the server. We can also use nslookup to test DNS server from the client. By nslookup we can check that client can connect the server.
Write a program that reads a list of words. Then, the program outputs those words and their frequencies. Ex: If the input is: hey hi Mark hi mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1
Answer:
#Declare variable to get the input
#list from the user
input_list = input()
#split the list into words by space
list = input_list.split()
#Begin for-loop to iterate each word
#to get the word frequency
for word in list:
#get the frequency for each word
frequency=list.count(word)
#print word and frequency
print(word,frequency)
Explanation:
This program that we are told to write will be done by using python programming language/ High-level programming language.
The question wants us to write a program in which the output will be as below;
hey 1
hi 2
Mark 1
hi 2
mark 1
Just by imputing hey hi mark hi mark.
Just copy and run the code below.
#Declare variable to get the input
#list from the user
input_list = input()
#split the list into words by space
list = input_list.split()
#Begin for-loop to iterate each word
#to get the word frequency
for word in list:
#get the frequency for each word
frequency=list.count(word)
#print word and frequency
print(word,frequency)
In this exercise we have to use the knowledge in computational language in python to write the following code:
We have the code can be found in the attached image.
So in an easier way we have that the code is
input_list = input()
list = input_list.split()
for word in list:
frequency=list.count(word)
print(word,frequency)

Write a function called unzip that takes as parameter a sequence (list or tuple) called seq of tuples with two elements. The function must return a tuple where the first element is a list with the first members of the seq tuple and the second element is a list with the second members of the seq tuple.
This example clarifies what is required:
Ist =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(Lst) lst tup
print(tup)
#prints ([1, 2, 3], ['one', two','three'7)
Answer:
Here is the function unzip:
def unzip(lst):
result= zip(*lst)
return list(result)
The complete program in Python is given below:
def unzip(lst):
result= zip(*lst)
return list(result)
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
Explanation:
Here zip() function is used in the unzip function. The return type of zip() function is a zip object. This means the function returns the iterator of tuples. This function can be used as its own inverse by using the * operator.
If you do not want to use zip() function then the above program can also be implemented as following which uses a for loop for elements in the given list (lst). This can make a pair of lists (2 tuple) instead of list of tuples:
def unzip(lst):
output = ([ a for a,b in lst ], [ b for a,b in lst ])
return output
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
The programs along with their output are attached.
What are the best data structures to create the following items? And why?
1. Designing a Card Game with 52 cards.
2. Online shopping cart (Amazon, eBay, Walmart, Cosco, Safeway, ...)
3. Online waiting list (De Anza College class waiting list, ...)
4. Online Tickets (Flight tickets, concert tickets, ...)
Answer:
The best structures to create the following items are
ARRAYHASHMAPS QUEUE SORTED LINK LISTSExplanation:
The best structures to create the following items are:
Array : for the storage of cards in a card game the best data structure to be used should be the Array data structure. this is because the size of the data ( 52 cards ) is known and using Array will help with the storing of the cards values in the Game.Hashmaps : Hashmap data structure should be implemented in online shopping cart this IS BECAUSE items can be easily added or removed from the cart therefore there is a need to map the Items ID or name to its actual database online waiting list are usually organised/arranged in a first-in-first-out order and this organization is best created using the queue data structure Sorted link lists is the best data structure used to create, store and manage online tickets. the sorted link data structure helps to manage insertions and deletions of tickets in large numbers and it also reduces the stress involved in searching through a large number of tickets by keeping the tickets in sorted listsMax magnitude Write a method maxMagnitude() with two integer input parameters that returns the largest magnitude value. Use the method in a program that takes two integer inputs, and outputs the largest magnitude value. Ex: If the inputs are: 5 7 the method returns: 7 Ex: If the inputs are: -8 -2 the method returns: -8 Note: The method does not just return the largest value, which for -8 -2 would be -2. Though not necessary, you may use the absolute-value built-in math method. Your program must define and call a method: public static int maxMagnitude(int userVal1, int userVal2)
Answer:
The java program is as follows.
import java.lang.*;
public class Numbers
{
//variables to hold two numbers
static int num1=-8, num2=-2;
//method to return integer with higher magnitude
public static int maxMagnitude(int userVal1, int userVal2)
{
if(Math.abs(userVal1) > Math.abs(userVal2))
return userVal1;
else
return userVal2;
}
public static void main(String[] args) {
int max = maxMagnitude(num1, num2);
System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);
}
}
OUTPUT
The number with higher magnitude among -8 and -2 is -8
Explanation:
1. Two integer variables are declared to hold the two numbers. The variables are declared at class level (outside main()) and declared static.
2. The variables are initialized with any random value.
3. The method, maxMagnitude(), takes the two integer parameters and returns the number with higher magnitude. Hence, return type of the method is int.
public static int maxMagnitude(int userVal1, int userVal2)
4. This method finds the number with higher magnitude using the Math.abs() method inside if-else statement.
if(Math.abs(userVal1) > Math.abs(userVal2))
return userVal1;
else
return userVal2;
5. Inside main(), the method, maxMagnitude(), is called. This method takes the two variables as input parameters.
6. The integer returned by the method, maxMagnitude() is assigned to a local integer variable, max, as shown.
int max = maxMagnitude(num1, num2);
7. The result is displayed to the user as shown.
System.out.println("The number with higher magnitude among "+num1+ " and "+num2+ " is "+max);
8. The class variables and the method, maxMagnitude(), are declared static so that they can be used and called inside main().
9. The variable, max, is called local variable since it can be used only within the main() where it is declared. It is not declared static.
10. The class is declared public since it has the main() method and execution begins with main().
11. The program is saved with the same name as the name of the public class having main(). In this case, the program is saved as Numbers.java.
12. No user input is taken for the two input parameter values. The static variables can be assigned any integer value and the program can be tested accordingly.
A vSphere Administrator is receiving complaints a database VM is experiencing performance issues. The VM is a member of the high priority resource pool and the cluster has not experienced contention.
Which condition should be checked to address immediate performance concerns?
A. VM snapshots
B. VMFS version
C. Resource Pool share value
D. Configured CPU shares
Answer:
C. Resource Pool share value.
Explanation:
The vSphere is a term used to describe the VMware’s virtualization cloud platform. The vSphere comprises of the following, vCenter Server, ESXi, Virtual Machine File System (VMFS) and vCenter Client.
If a vSphere Administrator receive complaints that a database Virtual Machine (VM) is experiencing performance issues and the Virtual Machine (VM) is a member of the high priority resource pool and the cluster has not experienced contention.
In order to address immediate performance concerns, the vSphere Administrator should check the Resource Pool share value.
VMware resource pool refers to the aggregated central processing unit and memory allocated to a Virtual Machine (VM) for flexible management of the resources.
Also, the vSphere Administrator should install VMware tools to check which processes are having high CPU usage by using vimtop, as well as checking if vCenter Server is swapping.
