My main problem is understanding when multiple testcases are taken in a coding problem with the copy feature on sample case, how can I (or should I) get answer for each case after inputting all the cases(t==0)?

I’ve usually skimmed through this concept so please help me understand, following is one such example problem.

The first line contains an integer t
(1≤t≤104
) — the number of test cases.

The first and only line of each test case contains 4
integers a1
, a2
, b1
, b2
(1≤a1,a2,b1,b2≤10
) where a1
and a2
represent the cards Suneet has, and b1
and b2
represent the cards Slavic has, respectively.

test case :
5
3 8 2 6
1 1 1 1
10 10 2 2
1 1 10 10
3 8 7 2

output:
2
0
4
0
2

My solution:

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

int wins(int a1, int a2, int b1, int b2)
{
int w = 0;

if (a1-b1 > 0 && a2-b2 > 0) w+=2;
if (a1-b2 > 0 && a2-b1 > 0) w+=2;
  

return w;

}

int main() {

int t , w;
cin>>t;

while(t!=0) {
    int  a1, a2, b1, b2;
    cin>>a1>>a2>>b1>>b2;
    
    w = wins(a1,a2,b1,b2);
    cout<<w<<endl;
    t--;
}

return 0 ;

}
