INTEST : Time Limit Exceeded in C++

I am trying to test my I/O methods via problem: INTEST http://www.codechef.com/problems/INTEST. On submitting it says time-limit exceeded. I previously submitted the similar problem in C, which gets accepted and takes 1.3 sec but for C++, its going beyond 8 sec. Is there any serious bug in my code or my I/O method is really so bad. Please help guys. As I am trying to switch from C to C++, its really demoralizing. Here is my source code:

#include <iostream>
using namespace std;

int main(){
  int test, div;
  cin >> test >> div;
  int count = 0;
  int num;
  while(test--){
    cin >> num;
    count += (num%div ? 0 : 1);  
  }
  cout << count << endl;
  return 0;
}
