Question

C++这道题应该怎么做？

设计Time类和Date类，要求设计一个Birthtime类，它继承了Time类和Date类，并且还有一项出生孩子的名字Childname，同时设计主程序显示一个小孩的出生时间和名字.

Answer 1

代码如下：#include <iostream>#include <string> class Time{public: Time(int hour, int minute, int second) :m_hour(hour) ,m_minute(minute) ,m_second(second) {} inline std::string TellTime() { return std::to_string(m_hour) + " h " + std::to_string(m_minute) + " m " + std::to_string(m_second) + " s "; } protected: int m_hour; int m_minute; int m_second; }; class Date{public: Date(int year, int month, int day) :m_year(year) ,m_month(month) ,m_day(day) {} inline std::string TellDate() { return std::to_string(m_year) + " Y " + std::to_string(m_month) + " M " + std::to_string(m_day) + " D "; } protected: int m_year; int m_month; int m_day;}; class BirthTime : public Time, Date{public: BirthTime(std::string name, int hour, int minute, int second, int year, int month, int day) :Time(hour, minute, second) ,Date(year, month, day) {} void TellBirthDay() { std::cout<<TellDate() + TellTime()<<std::endl; } private: std::string m_name;}; int main(){ BirthTime bt("Lucy", 12, 45, 10, 1990, 4, 9); bt.TellBirthDay(); return 0;}

Answer 2

class Birthtime extends Time,Date{
public String Childname;
public Birthtime(String Childname){
Childname=this. Childname;
}
public static void main(String a[]){
这里写输出内容：
}
接下来 定义 Time类和Date即可。
