C Language Loop Control - Quiz

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 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: In a for loop, which part is optional?

A. Initialization
B. Condition
C. Increment/Decrement
D. All parts are mandatory

Correct Option: C
Remarks:

Explanation:

While initialization and condition are mandatory in a for loop, the increment or decrement part is optional.

Q: Which loop control statement is used to skip the remaining code in the current iteration and proceed to the next iteration?

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

Correct Option: A
Remarks:

Explanation:

The "continue" statement is used to skip the remaining code within the current iteration and move to the next iteration.

Q: What happens if the loop condition is initially false in a do-while loop?

A. The loop executes once and terminates
B. The loop does not execute at all
C. The loop executes indefinitely
D. The loop executes but skips the first iteration

Correct Option: A
Remarks:

Explanation:

In a do-while loop, the loop body is executed at least once even if the condition is initially false.

Q: Which loop control statement is used to exit from the loop and transfer control to the statement immediately after the loop?

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

Correct Option: A
Remarks:

Explanation:

The "break" statement is used to terminate the loop and continue execution after the loop's closing brace.

Q: What is the purpose of the "do-while" loop?

A. To execute code based on a condition
B. To execute code repeatedly until a condition is false
C. To execute code at least once and then based on a condition
D. To execute code based on multiple conditions

Correct Option: C
Remarks:

Explanation:

The "do-while" loop ensures that the code block is executed at least once before checking the loop condition for further execution.

Q: When one loop is used within another loop, it is said to be a _______________.

A. outer loop
B. inner loop
C. nested loop
D. none of these

Correct Option: C
Remarks:

Explanation:

nested loop

Certainly! Here is an example of a nested loop in Java:


public class NestedLoopExample {
    public static void main(String[] args) {
        // Outer loop
        for (int i = 1; i <= 3; i++) {
            System.out.println("Outer loop iteration: " + i);

            // Inner loop
            for (int j = 1; j <= 2; j++) {
                System.out.println("  Inner loop iteration: " + j);
            }
        }
    }
}

Output:


Outer loop iteration: 1
  Inner loop iteration: 1
  Inner loop iteration: 2
Outer loop iteration: 2
  Inner loop iteration: 1
  Inner loop iteration: 2
Outer loop iteration: 3
  Inner loop iteration: 1
  Inner loop iteration: 2

In this example, the outer loop runs 3 times, and for each iteration of the outer loop, the inner loop runs 2 times. This demonstrates how nested loops work in Java.
