一个类的编程的问题

#include <iostream.h>
#include "Myfather.h"


  Mysister::Mysister():Myfather(17,100)
    {
   
   
    }

    void Mysister::fathertemper()
    {
        cout<<"she is beautiful"<<endl;
   
    }




Compiling...
Mysister.cpp

执行 cl.exe 时出错.

Mysister.obj - 1 error(s), 0 warning(s)



我只是在基类中有个子类Mysister，来编写，报错了啊！找不到愿因。
