C++ 输入两个整形数据 输出求和求积

Answer 1

#include "iostream"
using namespace std;
int mian()
{
int a = 0;
int b = 0;
cout<<"输入整数a：";
cin>>a;
cout<<"输入整数b：";
cin>>b;
cout<<a*b;<<endl;
cout<<a+b;
raturn 0;
}

Answer 2

//修改自楼上
#include "iostream"
using namespace std;
int main() /*拼写错误*/
{
int a = 0;
int b = 0;
cout<<"输入整数a：";
cin>>a;
cout<<"输入整数b：";
cin>>b;
cout<<a*b<<endl; //分号错误
cout<<a+b;
return 0; //拼写错误
}

Answer 3

#include <iostream>
using namespace std;
void main()
{
int a ,b;
cout<<"请输入两个整数："<<endl;
cin>>a>>b;
cout<<"这两个数相乘为："<<a*b<<"这两个数相加为："<<a+b;
}

比较简单明了吧！！
