一、教学目的： 能理解C++中运算符重载的需要性

#include<fstream.h>
#include"student.cpp"
#include"master.cpp"

void main()
{
	ofstream out("abc.txt");

	student s1("Dill Arnson",12567,3.5);
	MasterStudent s2("Welch Shammas", 12667,4.1,'A');
	MasterStudent s3("Portel Braumbel",12579,3.8,'B');


	out<<s1;
	out<<s2;
	out<<s3;
}
