Answer with Explanation

To convert the given for loop into an exit-controlled loop (i.e., a do-while loop), we need to ensure that the loop body executes at least once before checking the condition.

Converted Code Using do-while Loop:


int a = 10, b = 1;

do {
    b += a;
    b++;
    a -= 2;
} while (a >= 1);

System.out.print(b);

Explanation:

  1. Initialization: a = 10, b = 1

  2. Loop Execution: The loop executes at least once before checking a >= 1.

  3. Update: a is decremented by 2 in each iteration.

  4. Condition Check: The loop continues as long as a >= 1.

This ensures the loop behaves the same way as the original for loop but follows an exit-controlled structure.
