student.h

一、教学目的： 能理解C++中运算符重载的需要性

#include<iostream.h>
#include<string.h>
#ifndef STUDENT
#define STUDENT
//大学生类
class student
{
public:
	student(char*ps,unsigned num,float g)
	{
		strcpy(pName,ps);
		uID=num;
		grade=g;
	}
	virtual void display(ostream& out);
protected:
	char pName[20];
	unsigned int uID;
	float grade;
};
ostream& operator<<(ostream& out,student& st);
#endif
