ATM showing wrong answer in C++

#include<iostream>
#include<iomanip>
using namespace std;
int main() {
    int X;
    double Y;
    cout<<X<<" "<<fixed<<setprecision(2)<<Y<<endl;
    if(0<X<=2000 && 0<=Y<2000 && X<=Y+0.50 && X%5==0) {

        cout<<Y-X-0.50<<endl;
        }else{
            cout<<Y<<endl;
        }
    return 0;
    }
