This is my code before:(language is C++)

#include<bits/stdc++.h>
#define int long long
using namespace std;
int a,b;
signed main(){
	cin>>a>>b;
	cout<<int((a+b*0.1)/1.9);
	return 0;
}

GCC says: "#define int long long is wrong" But I think int and long long is not wrong.

This is my AC code(language is C++ to):

#include<bits/stdc++.h>
//#define int long long
using namespace std;
int a,b;
signed main(){
	cin>>a>>b;
	cout<<int((a+b*0.1)/1.9);
	return 0;
}

Thank for your help!!!
