我是新手，求高手帮我看看下面这个程序....
程序分为以下几个部分：student.h
#ifndef SHAPE_H
#define SHAPE_H
struct credit
{
char course[20];
int hour;
char type[5];
};
class Student
{
protected:
char *name;
int student_ID;
credit credit_hour[10];
int num;
public:
Student();
virtual~Student(){};
char *getname();
virtual void InputInfo();
virtual void input_credit()=0;
virtual void displayInfo()=0;
virtual int GetStuNum();
};
class UnderGraduate:public Student
{public:
virtual void InputInfo();
virtual void Input_credit();
virtual void displayInfo();
int GetStuNum();
private:
static int StuNum;
};
class Graduate:public Student
{
public:
virtual void InputInfo();
virtual void input_credit();
virtual void displayInfo();
int GetStuNum();
private:
static int StuNum;
char *tutor;
};

程序有点长，求帮帮忙，小弟感激不尽...
程序有什么问题，说说才能有的放矢啊~~
