i don`t know what i should do to make the test right:


#include<iostream>
using namespace std;

int main()
{

int T, m, n, k, l,Result;
cin >> T;
if (T >= 1 && T <= 100)
{
for (int i = 0; i < T; i++)
{
cin >> m >> n >> k >> l;
if (k >= 1 && k <= m&&m <= 100000 && l >= 1 && l <= n && n <= 100000)
{
Result = (m*n) - (k*l);
}
cout << Result << endl;
}
}


}
