Question

what is the output of the below mentioned program and I need step by step explanation



int main()

{

int n = 12 , res = 1;

while( n > 3)

{

n -= 3;

res *= 3;

}

printf("%d" , n*res);

}

Answer 1

Answer:

81

Explanation:

while n>3 means it will stop even when n = 3

So, loop will run 3 times.

n = 12, 9, 6.

So, n = 3 as 6-3 = 3

and res = 1×3×3×3 = 27

So, n×res = 3×27 = 81
