class DoWhile { public static void main(String s[]) { int n = 3;
do { System.out.println("n = " + n); n--; } while ( n > 0 );
} }
n = 3 n = 2 n = 1
n = 3 n = 2 n = 1 n = 0
n = 3
Compilation errors
Correct Answer : A
Inside main, an integer variable n is declared and initialized to 3. Irrespective of the termination condition, the statements in do are executed first. The display statement prints n as 3 and then decrements n. The statements in the do-while body (display statement and n--) will be executed till the condition n > 0 returns false. Thus there will be 2 more iterations printing values of n as 2 and 1. When n reaches 0, condition is violated and control goes out of do-while loop.
