神经质写法：用到栈，格式化输入输出，stl容器。 话不多说，上代码！ #include <iostream> #include <stack> #include <stdio.h> using namespace std; int main(){ int cnt=0; stack<int>a; for(int i=0;i<=1;i++){ int x; scanf("%d",&x); a.push(x); } for(int i=0;i<=1;i++){ cnt+=a.top(); a.pop(); } printf("%d",cnt); return 0; }

直接上代码，看着就无语 #include<iostream> using namespace std; int main(){ int a,b; cin>>a>>b; cout<<a+b; }

难啊，太难了啊啊啊啊

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

#include<iostream>//stream流输入输出i/o using namespace std;s//std命名空间 int main(){//主函数 int a,b;//定义a,b两个变量 cin>>a>>b;//stream流输入 cout<<a+b;//stream流输出 return 0;//return结束好习惯 }

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

很简单，给你提示：cout<<a+b;

#include<iostream> using namespace std; int main(){ int a, b; cin >> a >> b; cout << a + b; return 0;} 有帮助就赞一个！！！！！！！

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