Why this code shows wrong?

Can anyone tell me why this code is not passed in Problem Code : INTEST ?

#include<iostream>
using namespace std;

int main()
{
    int cases,numb,flag,temp;
    cin>>cases>>numb;

    for (int i = 0; i<cases; i++)
    {
        cin>>temp;
        if (temp%numb == 0)
        {flag++;}
    }
    cout<<flag;
    return 0;
}

Pay attention to compiler warnings! :slight_smile:

please flag static

Initialise the flag to a particular value i.e 0

5

flag is a boolean type variable so define it like that or put particular value of flag .

6

Here the variable flag must be initialized.
