语言刚开始学,我也是一边看书一边改的..

C++ 测试题 题目要求：
设计一个学生类Student，包含的属性有姓名name、

年龄age、性别sex ; 并通过成员函数给他们赋值,还定义了纯虚函数以下两个派生类通过虚函数来访问其成员函数
由学生类派生出本科生类Undergraduate
和研究生类Graduate，其中本科生类包含的属性有姓名name、

年龄age、性别sex 学位degree ,并通过成员函数给他们赋值
研究生类
包含的属性有姓名name、年龄age、性别sex 学位degree并通过成员函数给他们赋值

要求在main方法中输出本科生王明的所有
属性("王明",23,男"本科",)
和研究生刘军的所有属性("刘军",27,""男"硕士",)。

语言刚开始学,我也是一边看书一边改的..后面怎么做请大家指导

#include <iostream.h>
class student
{ protected:
char *name;
int age;
char *sex;
public:
student(char*n,int a,char *s)
{name=n;
age=a;
sex=s;}
virtual void print()=0;};
class Undergraduate:pubic student
{int

这个题目很容易啊，呵呵，我先做做，做好发过来

能帮我看看改一改吗 做了一天头都大了....
不胜感谢!!
