PTA---C++实现，定义抽象类Person、派生类Student和类Teacher

问题描述：设计抽象类Person，派生出具体类：学生类Student和教师类Teacher，创建若干不同类对象后并在主方法中测试。
数据成员定义：
Person [ID，姓名，生日]
Student [专业，成绩]
Teacher [职称，工资]
带参构造方法分别为：
Person(int id,String name, int bir)
Student(int id,String name, int bir, String major,double score)
Teacher(int id,String name, int bir, String title, double salary)
toString方法(Eclipse自动生成)

输入格式：第一行整数n表示有n个对象，每个对象占2行，第一行为数字0（表示学生）或1（表示教师），第二行为生成对象的参数。

输出格式：按行输出具体对象的信息。

#include<iostream>
#include<iomanip>
using namespace std;
class Person{
	public:
		int ID; string Name; int Birthday;
		void Set(int id, string name, int birthday){ID=id;Name=name;Birthday=birthday;}
		void Print();		
};



class Student : public Person{
	public:
		string Major; double Score;
		void Set(int id, string name, int birthday, string major, double score){Person::Set(id,name,birthday);Major=major;Score=score;}
		void Print(){cout<<"Student [";Person::Print();cout<<"major="<<Major<<", score="<<fixed<<setprecision(1)<<Score<<"]"<<endl;}
};

Student *per[10];

class Teacher : public Person{
	public:
		string Title; double Salary;
		void Set(int id, string name, int birthday, string title, double salary){Person::Set(id,name,birthday);Title=title;Salary=salary;}
		void Print(){cout<<"Teacher [";Person::Print();cout<<"title="<<Title<<", salary="<<fixed<<setprecision(1)<<Salary<<"]"<<endl;}
};

Teacher *perr[10];

void Person::Print(){cout<<"id="<<ID<<", name="<<Name<<", bir="<<Birthday<<", ";}

int main(){
	Student *stu; Teacher *tea;
	int n, i, choice;
	cin>>n;
	for(i=0;i<n;i++){
		cin>>choice;
		if(choice==0){
			stu=new Student();
			cin>>stu->ID>>stu->Name>>stu->Birthday>>stu->Major>>stu->Score;
			per[i]=stu;}
		if(choice==1){
			tea=new Teacher();
			cin>>tea->ID>>tea->Name>>tea->Birthday>>tea->Title>>tea->Salary;
			perr[i]=tea;}
		}
	
	for(i=0;i<n;i++){
		if(per[i]){per[i]->Print();}
		else{perr[i]->Print();}}
	
	return 0;
}
