定义一个时间类Time,包含3个保护数据成员Hour（小时）,Minute（分钟）,second(秒)以及两个公有成员函数SetTime()用来为对象设置时间,ShowTime()用来输出显示时间.

#include
using namespace std;
class Time
{
protected:
int Hour;
int Minute;
int second;
public:
Time();
void SetTime(int Hour,int Minute,int second);
void ShowTime();
};
Time::Time()
{
Hour = 0;
Minute = 0;
second = 0;
}
void Time::SetTime(int Hour,int Minute,int second)
{
this->Hour = Hour;
this->Minute = Minute;
this->second = second;
}
void Time::ShowTime()
{
cout
