#include<iostream>

int main()
{
    std::cout<<"可以输入两个加数，本程序完成加法..."<<std::endl;
    int numbera=0,numberb=0;
    std::cin>>numbera>>numberb;
    std::cout<<numbera<<" + "<<numberb<<" = "<<(numbera+numberb)<<std::endl;
    return 0;
}

g++ -o main main.cpp 

[root@workstudio tmp]# ./main 
可以输入两个加数，本程序完成加法...
