```
#include <iostream>
#define int long long
using namespace std;
signed main()
{
int a,b;
cin >> a >> b;
cout << a+b;
return 0;
}
```

你这个代码要开long long
by banglee @ 2023-05-18 16:54:06
@[banglee](/user/681292) 你难道没注意到
```cpp
#define int long long
```

@[_really_myself_](/user/718390)
可能会被系统认为你定义的是int类型，而不是long long 类型
by banglee @ 2023-05-20 20:25:36
@[_really_myself_](/user/718390)
稳妥的做法就是直接
```cpp
long long a,b;
```
