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

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

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

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

#include <iostream>//头文件--工具箱 using namespace std; int a,b;//先定义a与b这两个变量，数据较小用int int main (){ cin>>a>>b;//输入 cout<<a+b;//输出 return 0; }

废话不多说 #include<iostream> using namespace std; int main(){ int n,m; cin>>n>>m; cout<<n+m; return 0; }

这道题目是可以cin和cout做的，但是为了节省空间，我用scanf和printf了。

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

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

#include<bits/stdc++.h> using namespace std; void add(int a,int b){ cout<<a+b; } int main(){ int a,b; cin>>a>>b; add(a,b); return 0; } 此处使用函数。（不愧是我）

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

#include<bits/stdc++.h> using namespace std; int main(){ int a; int b; scanf("%d%d",&a,&b); int c = a+b; printf("%d",c); return 0; }

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

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

#include<iostream> #include<algorithm> #include<string> #include<queue> #include<stack> #include<iomanip> #include<cmath> #include<cstdio> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a+b; }

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