大佬们，帮我看看这道题怎么改？

#include<bits/stdc++.h>
using namespace std;
int ix,iy,ia,ib;
long long x,y,a,b;
int main()
{
    scanf("%d%d",&ix,&iy);
    scanf("%d%d",&ia,&ib);
    ix = x;
    iy = y;
    ia = a;
    ib = b;
    if (x * a != ix * ia || x * b != ix * ib || y * a != iy * ia || y * b != iy * ib)
        cout<<"long long int";
    else
        cout<<"int";
    return  0;
}
