Question

(iv) Convert the given loop into exit controlled loop.


int a, b;

for ( a=10 , b=1; a>=1 ; a-=2)
{
    b+=a;
    b++;
}

System.out.print(b);

Accepted Answer

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:

 
Initialization: a = 10, b = 1

 
Loop Execution: The loop executes at least once before checking a >= 1.

 
Update: a is decremented by 2 in each iteration.

 
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.
