C | Loops & Control Structure | Question 9

  • Difficulty Level : Medium
  • Last Updated : 01 Jun, 2021

Output?




#include <stdio.h>
int main()
{
    int c = 5, no = 10;
    do {
        no /= c;
    } while(c--);
   
    printf ("%d\n", no);
    return 0;
}

(A) 1
(B) Runtime Error
(C) 0
(D) Compiler Error


Answer: (B)

Explanation: There is a bug in the above program. It goes inside the do-while loop for c = 0. Also as the increment is post increment, so (no/0) will create a divide by 0 error. So it fails during runtime.
