Question

求大神指点，为什么用c++编的程序输出结果后直接就自动退出了？

#include<string>;
#include<iostream>;
using namespace std;
int main()
{
int numa;
int numb;
cout<<"a = :"<<endl;
cin>>numa;
cin>>numb;
cout<<"he :"<<numa+numb<<endl;
cin.get();
return 0;
}

Answer 1

cin.get()会读取cin>>numb中输入时的回车符，读入回车就直接返回了。

试试这样行不行：

#include<string>;
#include<iostream>;
using namespace std;
int main()
{
int numa;
int numb;
cout<<"a = :"<<endl;
cin>>numa;
cin>>numb;
cout<<"he :"<<numa+numb<<endl;
cin>>numb;
return 0;
}

追问

太谢谢啦
