    for(x=-1; x<=10; x++){
        if(x < 5)
            continue;
        else
            break;
        printf("atnyla");
    }
    return 0;
}

A. Infinite times
B. 11 times
C. 0 times
D. 10 times

Correct Option: C
Remarks:

Explanation: Option C

Q:

How many times the while loop will get executed if a short int is 2 byte wide?

 
#include<stdio.h>
int main()
{
    int j=1;
    while(j <= 255)
    {
        printf("%c %d\n", j, j);
        j++;
    }
    return 0;
}

A. Infinite times
B. 255 times
C. 256 times
D. 254 times

Correct Option: A
Remarks:

Explanation:

Option B
The while(j <= 255) loop will get executed 255 times. The size short int(2 byte wide) does not affect the while() loop.

Q: Which of the following loop control statements is used to terminate a loop completely?

A. continue
B. break
C. exit
D. return

Correct Option: B
Remarks:

Explanation:

Answer: b) break

Explanation: The break statement is used to terminate a loop completely.

Q: Which of the following loop control statements is used to exit from a function or program?

A. continue
B. break
C. exit
D. return

Correct Option: C
Remarks:

Explanation:

Answer: c) exit

Explanation: The exit statement is used to exit from a function or program.

Q: Which of the following loop control statements is used to return a value from a function?

A. continue
B. break
C. exit
D. return

Correct Option: D
Remarks:

Explanation:

Answer: d) return

Explanation: The return statement is used to return a value from a function.

Q: Which of the following loop control statements is used to terminate the current iteration of a loop and continue with the next iteration?

A. continue
B. break
C. exit
D. return

Correct Option: A
Remarks:

Explanation:

Answer: a) continue

Explanation: The continue statement is used to skip the current iteration of a loop and continue with the next iteration.

Q: Which loop is most suitable for situations where the number of iterations is known beforehand?

A. for loop
B. while loop
C. do-while loop
D. if-else loop

Correct Option: A
Remarks:

Explanation:

The for loop is ideal for situations where the number of iterations is predetermined and specified in the loop header.

Q: Which loop is best suited for scenarios where you want to repeat a block of code while a condition is true?

A. for loop
B. while loop
C. do-while loop
D. if-else loop

Correct Option: B
Remarks:

Explanation:

The while loop repeatedly executes a block of code as long as the specified condition remains true.

Q: What is the purpose of the "break" statement in a loop?

A. To end the program
B. To skip the current iteration
C. To terminate the loop prematurely
D. To resume the loop from the next iteration

Correct Option: C
Remarks:

Explanation:

The "break" statement is used to exit the loop immediately, even if the loop condition is still true.

Q: Loop ______ the program code.

A. elongates
B. strengthens
C. reduces
D. none of these

Correct Option: C
Remarks:

Explanation:

Loop reduces the program code.

Using loops in programming helps to reduce redundancy by allowing a set of instructions to be executed repeatedly without having to write the same code multiple times. This makes the code more concise and easier to maintain.
