teacher.cpp

这个是继承与派生的实验

//teacher.cpp
#include<iostream.h>
#include<string.h>
#include"Teacher.h"
Teacher::Teacher():person()   //初始化
{
	title=NULL;
}
void Teacher::puttitle(const char*t)
{
	delete[]title;
    title=new char[strlen(t)+1];
	strcpy(title,t);
}
Teacher::~Teacher()
{delete[]title;}
void Teacher::print()
{
	person::print();
	cout<<"title="<<title<<endl;    //输出职称
}
