resps.append("Good for the flowers?")
elif percent > 50:
resps.append("Watch out for clouds!")
else:
resps.append("Nice day!")
for r in resps:
print(r)
Explanation:
*The code is in Python.
Create an empty list called resps
Initialize a list called percent_rain with some values
Create a for loop that iterates through the percent_rain. Check each value in the percent_rain and add the required strings to the resps using append method
Create another for loop that iterates throgh the resps and print the values so that you can see if your program is correct or not
Answer:

Consider the following concurrent tasks, in which each assignment statement executes atomically. Within a task, the statements occur in order. Initially, the shared variables x and y are set to 0.
Task 1 Task 2
x = 1 y = 1
a = y b = x
At the end of the concurrent tasks, the values ofa andb are examined. Which of the following must be true?
I. ( a == 0 ) ( b == 1 )
II. ( b == 0 ) ( a == 1 )
III. ( a == 1 ) ( b == 1 )
(A) I only
(B) II only
(C) III only
(D) I and II only
(E) I, II, and III
Answer:
(D) I and II only
Explanation:
Concurrent tasks is when there is more than one task to be performed but the order of the task is not determined. The tasks occur asynchronously which means multiple processors occur execute input instruction simultaneously. When x =1 and y = 1, the concurrent task will be performed and the a will be zero or either 1.
A new operating system uses passwords that consist of three characters. Each character must be a digit between 0 and 9. For example, three distinct possible passwords are 123, 416, and 999. The system uses 32-bit salt values. The system also allows one login attempt every second and never locks out users regardless of how many failed attempts occur. If an adversary has obtained a copy of the password file and conducts an offline brute-force attack by trying every password combination until the adversary obtains username and password combination. The use of a 32-bit salt value
Answer:
Brute force is technique that is used for cracking password
In this case the system uses only three characters(0-9). By applying Brute force attack in "hit and try" manner we easily crack the password.
Explanation:
Solution
There are a wide variety of password cracking mechanisms.Brute force is one of the popular password cracking technique.Brute force attack is generally used to crack small passwords.
In the given example the system uses only three characters(0-9).By using Brute force attack in "hit and try" manner we easily crack the password.There are only 10 possible passwords for this type of system.Because we can arrange 0-9 only in 10 ways.But for Systems with long passwords it is difficult to find it in hit and try manner.But instead of having plain password each password have a random salt value.
In a system of 32 bit salt value there are 2^32 different key values.
By increasing the salt value from 32 bits to 64 bits there are 2^64 different key values.It increases the time taken to crack a password for an attacker.so by changing salt value from 32 to 64 bits will make it more harder for the adversary's attack to be successful.
Write a function PrintShampooInstructions(), with int parameter numCycles, and void return type. If numCycles is less than 1, print "Too few.". If more than 4, print "Too many.". Else, print "N: Lather and rinse." numCycles times, where N is the cycle number, followed by "Done.". End with a newline. Example output for numCycles = 2:
1: Lather and rinse.
2: Lather and rinse.
Done.
Hint: Define and use a loop variable.
Sample program:
#include
using namespace std;
int main() {
PrintShampooInstructions(2);
return 0;
}
Answer:
public static void PrintShampooInstructions(int numberOfCycles){
if (numberOfCycles<1){
System.out.println("Too Few");
}
else if(numberOfCycles>4){
System.out.println("Too many");
}
else
for(int i = 1; i<=numberOfCycles; i++){
System.out.println(i +": Lather and rinse");
}
System.out.println("Done");
}
Explanation:
I have used Java Programming language to solve this
Use if...elseif and else statement to determine and print "Too Few" or "Too Many".
If within range use a for loop to print the number of times
Answer:
#In Python
def shampoo_instructions(num_cycles):

Given the array [13, 1, 3, 2, 8, 21, 5, 1] suppose we choose the pivot to be 1 the second element in the array. Which of the following would be valid partitions?
A. 1 [1, 2, 3, 5, 8, 13, 21]
B. 1 [13, 1, 3, 2, 8, 21, 5]
C. 1 [13, 3, 2, 8, 21, 5, 1]
D. [1] 1 [13, 3, 2, 8, 21, 5]
E. [13] 1 [3, 2, 8, 21, 5, 1]
F. [13, 1, 3, 2, 8, 21, 5] 1 2/4
Answer:
D. [1] 1 [13, 3, 2, 8, 21, 5]
Explanation:
Using a quicksort with 1 as the pivot point, elements less than 1 will be sorted to the left of 1 and the other elements are greater than one will be sorted to the right of 1. The order doesn't matter. So we sort [1] to the left of 1 and [13, 3, 2, 8, 21, 5] to the right of 1. So, D. [1] 1 [13, 3, 2, 8, 21, 5] is the valid partition.

Account Balance Design a hierarchy chart or flowchart for a program that calculates the current balance in a savings account. The program must ask the user for:________.
A- The starting balance
B- The total dollar amount of deposits made
C- The total dollar amount of withdrawals made
D- The monthly interest rate
Once the program calculates the current balance, it should be displayed on the screen.
Answer:
a. starting balance
Explanation:
A program that calculates the current balance of a savings should ask the user for the starting balance and then ask for the annual interest rate. A loop should then iterate once for every month of the savings period in order to perform other tasks such as asking the user for the total amount deposited into the account, the total amount withdrawn from the account, and calculate the interest rate. The program will then proceed to display the result at the end of the savings period.
Write a program in python that can compare the unit (perlb) cost of sugar sold in packages with different weights and prices. The program prompts the user to enter the weight and price of package 1, then does the same for package 2, and displays the results to indicate sugar in which package has a better price. It is assumed that the weight of all packages is measured in lb. The program should check to be sure that both the inputs of weight and price are both positive values.
Answer:
weight1 = float(input("Enter the weight of first package: "))
price1 = float(input("Enter the price of first package: "))
weight2 = float(input("Enter the weight of second package: "))
price2 = float(input("Enter the price of second package: "))
if weight1 > 0 and price1 > 0 and weight2 > 0 and price2 > 0:
unit_cost1 = price1 / weight1
unit_cost2 = price2 / weight2
if unit_cost1 < unit_cost2:
print("Package 1 has a better price.")
else:
print("Package 2 has a better price.")
else:
print("All the entered values must be positive!")
Explanation:
*The code is in Python.
Ask the user to enter the weight and the price of the packages
Check if the all the values are greater than 0. If they are, calculate the unit price of the packages, divide the prices by weights. Then, compare the unit prices. The package with a smaller unit price has a better price.
If all the entered values are not greater than 0, print a warning message
Two of the most fundamental functions for dealing with interprocess communication are read() and write(). Consider the following otherwise valid C program:int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Select each of the following answers that is correct. CAN BE MULTIPLE CHOICES...
(1) The read() call may block until data becomes available
(2) When the read() call returns, this one call will return all of the data that was sent through the pipe, which is different behavior than if this was a socket
(3) If the read() call blocks, the process will be suspended until data arrives
(4) The write() call will return before all of the data has been written, if the corresponding read() call blocks mid-transfer
(5) Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe
Answer: Provided in the explanation section
Explanation:
int r, pipeFDs[2];
char message[512];
pid_t spawnpid;
pipe(pipeFDs);
spawnpid = fork();
switch (spawnpid)
{
case 0:
close(pipeFDs[0]); // close the input file descriptor
write(pipeFDs[1], "hi process, this is the STUFF!!", 21);
break;
default:
close(pipeFDs[1]); // close output file descriptor
r = read(pipeFDs[0], message, sizeof(message));
printf("Message received from other: %s\n", message);
break;
}
Observation of the program:
The read() call may block until data becomes available If the read() call blocks, the process will be suspended until data arrives Pipes can fill, which will cause the write() call to block until the read() call is able to read data from the pipe⇒ Therefore,Option 1,3 and 5 correct

Create a Python program that: Allows the user to enter a person's first name and last name. The user should be able to enter as many names as they desire. Create a function that takes the first name and last name, puts them together with the last name first, followed by the first name; with the names separated by commas. Take the result from the function, and place the resulting name in a list. Once the user finishes entering names, sort the contents of the list. Write the sorted names from a list into a text file. When you create the text file, allow the user to enter a name for the file to be created. After you finish writing names to the file, close the file and end the program.

In this assignment, you will develop a C++ program and a flowchart that calculates a cost to replace all tablets and desktop computers in a business. Customers paying cash get a ten percent discount applied to the total cost of the computers (desktop and tablets). Customers financing the purchase incur a fifteen percent finance charge based on the total cost of the computers (desktop and tablets). Tablets costs $320.00 each and desktops costs $800.00 each. The tax is 75% (.075).
Requirements:
⦁ Use the following variables of the appropriate type: name of company selling the computers, the cost per each type of computer, number of computers to be purchased, discount if paying cash, sales tax rate. Tablets =$320 each and desktop computers = $800.00 each. Sales Tax Rate = .075, Discount Percent = .10, and Finance Charge = .15.
⦁ Variable names must be descriptive.
⦁ Use additional variables to hold subtotals and totals.
⦁ For customers paying cash, the discount should be subtracted from the total computer cost.
⦁ For customers financing the purchase, the finance charge should be added to the total computer cost.
⦁ The body of your program must use variables only; there should not be any "hard coded" values in the output statements. An example of hardcoding is
***Cost of tablets = 4 * 320****.
⦁ Use cout to output the values of the variables to the console. Your cout statement MUST use the variables to display the values
⦁ Display the cost of the computers, tax and average cost per computer. The average cost will be the total cost divided by the number of computers purchased. Display the discount if the customer decides to pay cash or the finance charge if the customer finances the purchase.
⦁ Output must be labelled and easy to read as shown in the sample output below.
⦁ Program must be documented with the following:
⦁ // Name
⦁ // Date
⦁ // Program Name
⦁ // Description
⦁ Develop a flowchart
Hints:
Total cost of computers = cost per tablet * number of tablets purchased + cost per desktop * number of desktops purchased
Calculate the cost if paying cash or financing
Calculate the tax
Average cost per computer = Total computer cost divided by the number of computers purchased

TCPDump is used by Wireshark to capture packets while Wireshark own function is:
a. to provide a graphical user interface (GUI) and several capture filters.
b. to act as an intrusion prevention system (IPS) by stopping packets from a black-listed website or packets with payloads of viruses.
c. to defend the network against TCP SYN Flooding attacks by filtering out unnecessary TCP packets.
d. yet to be defined.
Answer:
a. to provide a graphical user interface (GUI) and several capture filters
Explanation:
TcPDump is a command line tool used to capture packets. TcPDump is used to filter packets after a capture has been done. To control network interfaces, TcPDump need to be assigned root privileges. Data is represented in form of text
Wireshark provide a graphical user interface (GUI) and several capture filters. It is a graphical tool used in packet capture analysis. Data is represented in wireshark as text in boxes.

Answer:
There's nothing wrong with the question you posted except that it's not well presented or arranged.
When properly formatted, the program will be error free and it'll run properly.
The programming language used in the question is Java programming lamguage.
in java, the sign ";" signifies the end of each line and lines that begins with // represent comments. Using this understanding of end of lines and comments, the formatted code goes thus
import java.util.Scanner;
public class Arraysum {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
final int NUM_ELEMENTS = 8;
// Number of elements
int[] userVals = new int[NUM_ELEMENTS];
// User numbers
int i = 0;
// Loop index
int sumVal = 0;
// For computing sum
// Prompt user to populate array
System.out.println("Enter " + NUM_ELEMENTS + " integer values...");
for (i = 0; i < NUM_ELEMENTS; ++i) {
System.out.print("Value: ");
userVals[i] = scnr.nextInt();
}
// Determine sum
sumVal = 0;
for (i = 0; i < NUM_ELEMENTS; ++i)
{
sumVal = sumVal + userVals[i];
}
System.out.println("Sum: " + sumVal); return;
}
}

The new Director of Information Technology has asked you to recommend a strategy to upgrade the servers on their network. Recommendations on server hardware, CPU chip set, speed, and caching are needed. You should also recommend which servers to upgrade first and determine whether any servers are still appropriate to keep.
Answer:
servers to be upgraded are : APPLICATION AND LOAD BALANCING SERVERS
servers still appropriate to use : DNS AND DHCP SERVERS
Explanation:
The recommendations to be made in line with what the new director of information is asking for includes :
1 ) For the servers to be upgraded : The servers that requires upgrades includes the APPLICATION SERVER and LOAD BALANCING SERVER. this is because these two servers are critical to the growth/expansion of any business, and they handle large volume of data
Recommendations on the servers upgrade includes:
Hardware : 2.3 GHz Intel Xeon Gold 5118 12-Core
CPU chip set : Socket: FCLGA3647, Type: NSBM
Speed : processor 3.2 GHz
caching: > 100 Gb
2) For servers that do not necessarily need to be upgraded : The servers that do not need immediate upgrade are DNS and DHCP
