为什么这个c++程序运行到后面运行终止

Question

程序程序源码如下：

#include "stdafx.h"
#include

using namespace std;

int _tmain(int argc, _TCHAR* argv[])
{
char firstname[20];
char lastname[20];
char grade;
int age;

cout << "what is your first name? ";
cin.getline(firstname,20);
cout << "what is your last name? ";
cin.getline(lastname,20);
cout << "what letter grade do you deserve? ";
cin >> grade;
cout << "what is your age? ";
cin >> age;

cout << "Name:" << lastname << "," << firstname << endl;
cout << "Grade:" << grade << endl;
cout << "Age:" << age << endl;
return 0;

}

在运行到cin>>age;时，我输入年龄后就直接被终止程序了是为什么，为什么后面的代码运行不了了？？求指教

Answer 1

后面的代码是运行了的，只不过太快，一闪而过啦。
可以在return 0的前面加一个getchar();
