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

#include<iostream> using namespace std; int main(){ long long a,b;//定义 cin>>a>>b;//输入 cout<<a+b;//输出 return 0; }

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

#include <iostream> using namespace std; int main(){ int a, b; cin>>a>>b; cout<<a+b; }

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

#include<iostream> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a+b; }

#include <bits/stdc++.h> using namespace std; short a,b; int main() { cin>>a>>b; cout<<a+b; return 0; }

这是一道非常水的题，直接A+B就行了 上代码：

#include<bits/stdc++.h> using namespace std; int main(){ int a, b; cin >> a >> b; cout << a + b; }
