#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<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(){ 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; vector<int> Next(string c){ vector<int>next; next.push_back(0); for(int i=1,j=0;i<c.length();i++){ while(j>0&&c[j]!=c[i]){ j=next[j-1]; } if(c[i]==c[j]){ j++; } next.push_back(j); } return next; } int main(){ string a,c; cin>>a>>c; vector<int> next= Next(c); for(int i=0,j=0;i<a.length();i++){ while(j>0&&a[i]!=c[j]){ j=next[j-1]; } if(a[i]c[j]) j++; if(jc.length()){ cout<<i-j+2<<endl; j=next[j-1]; } } for(int i=0;i<next.size();i++){ cout<<next[i]<<" "; } return 0; }

#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; }
