student.cpp

一、教学目的： 能理解C++中运算符重载的需要性

#include"student.h"
#include<iomanip.h>
#include<iostream.h>
void student::display(ostream& out)
{
	out<<setiosflags(ios::left)<<setw(20)<<pName
		<<uID<<","
		<<setiosflags(ios::right)<<setw(4)<<grade;
}
//插入操作符
ostream& operator<<(ostream& out,student& st)
{
	st.display(out);
	out<<endl;
	return out;
}
