Description

已知類如下：
（1） BirthDate（生日類） 含有：year,month,day 等資料成員
（2） Teacher（教師類）含有：num,name,sex 等資料成員
（3） Professor（教授類）含有：教師類和生日類的資料成員
要求：
（1）通過對Teacher和BirthDate使用繼承和組合的方式設計Professor
（2）定義Professor類物件prof，並給出所有資料的初值
（3）修改prof的生日資料
（4）輸出prof的全部最新資料

Input

 num,name,sex,year,month,day 和修改後的year,month,day

Output

 num,name,sex,year,month,day 

Sample Input

2001 Huang m
1970 1 1
1994 5 26

Sample Output

num:2001
name:Huang
sex:m
birthday:1994/5/26

HINT

 前置程式碼及型別定義已給定如下，提交時不需要包含，會自動新增到程式前部


/* C++程式碼 */

#include <iostream>

#include <string>

using namespace std;

class BirthDate {

public:

    BirthDate(int,int,int);

    void display();

    void setbirthday(int,int,int);

private:

    int year;

    int month;

    int day;

};

class Teacher

{

public:

    Teacher(int,string,char);

    void display();

private:

    int num;

    string name;

    char sex;

};


class Professor:public Teacher

{

public:

    Professor(int,string,char,BirthDate);

    void display();

    void setbirthday(int,int,int);

private:

    BirthDate birthday;

};


主函式已給定如下，提交時不需要包含，會自動新增到程式尾部

/* C++程式碼 */

int main()

{

    int num;

    string name;

    char sex;

    int year,month,day;

    cin>>num>>name>>sex;

    cin>>year>>month>>day;

    Professor prof(num,name,sex,BirthDate(year,month,day));

    cin>>year>>month>>day;

    prof.setbirthday(year,month,day);

    prof.display();

    return 0;

}
