Answer:
The program written in C language is as follows
#include<stdio.h>
int main()
{
//Declare digit
int digit;
//Prompt user for input
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit);
//Check if digit is within range 10 to 100
while(digit<10 || digit >100)
{
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit);
}
//Initialize counter to 0
int counter = 0;
for(int i=digit;i>0;i--)
{
printf("%3d", i); //Print individual digit
counter++;
if(counter == 10) //Check if printed digit is up to 10
{
printf("\n"); //If yes, print a new line
counter=0; //And reset counter to 0
}
}
}
Explanation:
int digit; ->This line declares digit as type int
printf("Enter any integer: [10 - 100]: "); -> This line prompts user for input
scanf("%d", &digit);-> The input us saved in digit
while(digit<10 || digit >100) {
printf("Enter any integer: [10 - 100]: ");
scanf("%d", &digit); }
->The above lines checks if input number is between 10 and 100
int counter = 0; -> Declare and set a counter variable to 0
for(int i=digit;i>0;i--){ -> Iterate from user input to 0
printf("%3d", i); -> This line prints individual digits with 3 line spacing
counter++; -> This line increments counter by 1
if(counter == 10){-> This line checks if printed digit is up to 10
printf("\n"); -> If yes, a new line is printed
counter=0;} -> Reset counter to 0
} - > End of iteration
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
Answer: Provided in the explanation section
Explanation:
The Question says;
Identify a logical operation (along
with a corresponding mask) that, when
applied to an input string of 8 bits,
produces an output string of all 0s if and
only if the input string is 10000001.
The Answer (Explanation):
XOR, exclusive OR only gives 1 when both the bits are different.
So, if we want to have all 0s, and the for input only 10000001, then we have only one operation which satisfies this condition - XOR 10000001. AND
with 00000000 would also give 0,
but it would give 0 with all the inputs, not just 10000001.

Remember to save _____ and be certain that you have your files saved before closing out.
Part 1: For this assignment, call it assign0 Implement the following library and driver program under assign0: Your library will be consisting of myio.h and myio.c. The function prototypes as well as more explanations are listed in myio.h. Please download it and accordingly implement the exported functions in myio.c. Basically, you are asked to develop a simple I/O library which exports a few functions to simplify the reading of an integer, a double, and more importantly a string (whole line). In contrast to standard I/O functions that can read strings (e.g., scanf with "%s", fgets) into a given static size buffer, your function should read the given input line of characters terminated by a newline character into a dynamically allocated and resized buffer based on the length of the given input line. Also your functions should check for possible errors (e.g., not an integer, not a double, illigal input, no memory etc.) and appropriately handle them. Then write a driver program driver.c that can simply use the functions from myio library. Specifically, your driver program should get four command-line arguments: x y z output_filename. It then prompts/reads x many integers, y many doubles, and z many lines, and prints them into a file called output_filename.txt. Possible errors should be printed on stderr.

Suppose you have 9 coins and one of them is heavier than others. Other 8 coins weight equally. You are also given a balance. Develop and algorithm to determine the heavy coin using only two measurements with the help of the balance. Clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
Answer:
Following are the algorithm to this question:
Find_Heavier_Coins(Coin[9]):
i) Let Coin[] Array represent all Coins.
ii) Divide coin[] into 3 parallel bundles and each has three coins, example 0-2, 3-5, 6-8 indicate a1 a2 a3
iii) Randomly select any two bundles and place them in balance [say a1 and a2]
iv) If Weigh of a1 and a2 has same:
// checking that if a3 has heavier coin
Choose any two 6-8 coins and place them onto balance [say 6 and 8]
If those who weigh has the same weight:
Third coin is coin heavier [say 7]
else:
The coin [6 or 8] is the one which is heavier on the balance
else:
//The coin has the package which would be heavier on the balance [say a1]
Select any two coins on balance from of the heavier package [say 0 and 1]
If they weigh the same weight:
Third coin is coin heavier [say 2]
else:
The coin that is heavier on the balance is the [or 0]
Explanation:
In the above-given algorithm code, a method Find_Heavier_Coins is declared which passes a coin[] array variable in its parameters. In the next step, if conditional block is used that checks the values which can be described as follows:
In the first, if block is used that checks a1 and a2 values and uses another if block in this it will print a3 value, else it will print 6 to 8 value. In the another, if the block it will check third coins value and prints its value if it is not correct it will print first coin valueAnyone help pls ?

Write an INSERT statement that adds these rows to the Invoice_Line_Items table:
invoice_sequence: 1 2
account_number: 160 527
line_item_amount: $180.23 $254.35
line_item_description: Hard drive Exchange Server update
Set the invoice_id column of these two rows to the invoice ID that was generated
by MySQL for the invoice you added in exercise 4.
Answer:
Insertion query for first row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (1, 160, '$180.23', "Hard drive Exchange");
Insertion query for second row :
INSERT into Invoice_Line_Items (invoice_sequence, account_number, line_item_amount, line_item_description) Values (2, 527, '$254.35', "Server update");
Explanation:
* In SQL for insertion query, we use INSERT keyword which comes under DML (Data manipulation Language).
* Statement is given below -
INSERT into Table_name (column1, column2, ....column N) Values (value1, value2, .....value N);
* With the use of INSERT query we can insert value in multiple rows at a same time in a table which reduces our work load.

Compute -ABE16-DF416 using 15’s complement
Answer:
33600
Explanation:
Let M = ABE16
and N = DF416
In hexadecimal representation: 10 = A, 11 = B, 12 = C, 13 = D, 14 = E, 15 = F
Step 1: Find the 15's complement of N
F F F F F
- D F 4 1 6
2 0 B E 9
Step 2: Add 15's complement of N to M
A B E 1 6
+ 2 0 B E 9
C C 9 F F
Step 3: Find the 15's complement of CC9FF
F F F F F
- C C 9 F F
3 3 6 0 0
Therefore, ABE16 - DF416 using 15's complement is 33600

The following numbers are inserted into a linked list in this order:
10, 20, 30, 40, 50, 60
What would the following statements display?
pCur = head->next;
cout << pCur->data << " ";
cout << pCur->next->data << endl;
a) 20 30
b) 40 50
c) 10 20
d) 30 40
Answer:
A. 20 30
Explanation:
Given
Linked list: 10, 20, 30, 40, 50, 60
Required
The output of the following code segment
pCur = head->next;
cout << pCur->data << " ";
cout << pCur->next->data << endl;
A linked list operates by the use of nodes which begins from the head to the next node, to the next, till it reaches the last;
The first line of the code segment; "pCur = head->next; " shifts the node from the head to the next node
The head node is the node at index 0 and that is 10;
This means that the focus has been shifted to the next at index 1 and that is 20;
So, pCur = 20
The next line of the code segment; cout << pCur->data << " "; prints pCur and a blank space
i.e. "20 " [Take note of the blank space after 20]
The last line "cout << pCur->next->data << endl; " contains two instructions which are
1. pCur = next->data;
2. cout<<pCur->data;
(1) shifts focus to the next node after 20 ; This gives pCur = 30
(2) prints the value of pCur
Hence, the output of the code segment is 20 30
) If FIFO page replacement is used with five page frames and eight pages, how many page faults will occur with the reference string 236571345157245 if the five frames are initially empty?
Answer:
There are a total of 8 page faults.
Explanation:
In FIFO page replacement, the requests are executed as they are received. The solution is provided in the attached figure. The steps are as follows
Look for the digit in the pages. if they are available, there is no page fault. If the digit does not exist in the page frames it will result in an error.
Two-factor authentication can best be breached by the adversary using:________. a. social engineering attack b. using sniffers like Wireshark and capturing packets c. using rootkits and privilege escalation to get to the kernel processes d. using a virus and destroying the computer that stores authentication information.
Answer:
a. social engineering attack
Explanation:
Two-factor authentication requires that the user/owner of the account enter a second verification code alongside their password in order to access the account. This code is usually sent to a personal phone number or email address. Therefore in order to breach such a security measure the best options is a social engineering attack. These are attacks that are accomplished through human interactions, using psychological manipulation in order to trick the victim into making a mistake or giving away that private information such as the verification code or access to the private email.
Write a basic program that performs simple file and mathematical operations.
a. Write a program that reads 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 find() 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.
b. After the program is working as above, modify the program so that it reads all dates from an input file "inputDates.txt" (an Example file is attached).
c. Modify your program further so that after parsing all dates from the input file "inputDates.txt", it writes out the correct ones into an output file called: "parsedDates.txt".
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
Answer:
Explanation:
I have written the Python program based on your requirements.
Just give the path of the input file and the path for the output file correctly where you want to place the output file.
In, my code - I have given my computer's path to the input and output file.

CASE II AziTech is considering the design of a new CPU for its new model of computer systems for 2021. It is considering choosing between two (2) CPU (CPUA and CPUB) implementations based on their performance. Both CPU are expected to have the same instruction set architecture. CPUA has a clock cycle time of 60 ns and CPUB has a clock cycle time of 75 ns. The same number of a particular instruction type is expected to be executed on both CPUs in order to determine which CPU would executes more instructions. CPUA is able to execute 2MB of instructions in 5*106 clock cycles. CPUB executes the same number of instructions in 3*106 clock cycles. a) Using the MIPS performance metric, which of the two (2) CPU should be selected to be implemented in the new computer system. Justify your choice. b) Compute the execution time for both CPUs. Which CPU is faster?
Answer:
(a)The CPU B should be selected for the new computer as it has a low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A.
(b) The CPU B is faster because it executes the same number of instruction in a lesser time than the CPU A .
Explanation:
Solution
(a)With regards to the MIPS performance metric the CPU B should be chosen for the new computer as it low clock cycle time which implies that it will implement the process or quicker when compared to the CPU A and when we look at the amount of process done by the system , the CPU B is faster when compared to other CPU and carries out same number of instruction in time.
The metric of response time for CPU B is lower than the CPU A and it has advantage over the other CPU and it has better amount as compared to CPU A, as CPU B is carrying out more execution is particular amount of time.
(b) The execution can be computed as follows:
Clock cycles taken for a program to finish * increased by the clock cycle time = the Clock cycles for a program * Clock cycle time
Thus
CPU A= 5*10^6 * 60*10^-9 →300*10^-3 →0.3 second (1 nano seconds =10^-9 second)
CPU B= 3 *10^6 * 75*10^-9 → 225*10^-3 → 0.225 second
Therefore,The CPU B is faster as it is executing the same number of instruction in a lesser time than the CPU A
