课本一道例题，运行不出来，

什么运行不出来？
至少把问题描述清除

ps  你的main函数漏了右括号

什么课本呀？

我加了右括号，程序也没有运行出来

谭浩强版的c++课本的一道例题，程序运行不出来啊

#include <string>
#include<iostream>
using  namespace  std;
class  Student
{
public:
       Student(int n,string nam,char s)
       {
           num=n;
           name=nam;
           sex=s;
       cout<<"Constructor  called."<<endl;

       }
LZ你应该是把Student写错了，应该是大写Student(int n,string nam,char s)

} 出了，你试试再

test

#include <string>

using namespace std;

        name = nam;
        sex = s;
        cout << "Constructor  called." << endl;
    }

    ~Student ()
    {

    }
};

    return  0;
}

    }
