Help me in solving VAD9V2 problem

My issue

I wrote the correct program, and answer is also correct, but you are showing its wrong, what’s the problem

My code

#include <bits/stdc++.h>
using namespace std;

int main() {

    int a = -50;
    int b = 40;
    // Update your code below this line
    int sum=a+b,product=a*b,quotient=a%b;

  return 0;

quotient is not a%b its a/b;
