1、1.1编写一个基于对象的程序，要求：（1）定义一个时间类 Time，类内有私有数据成员 hour（小时）、minute（分钟） 、sec（秒） ，公有成员函数 set_time()、show_time()。（2）set_time()函数和 show_time()函数在类内定义。set_time()作用是从键盘输入时间、分钟、秒的值，show_time()的作用是在屏幕上显示时间、分钟、秒的值。（3）在 main()函数定义 Time 类的对象 t1，并调用set_time()函数给时间赋值，调用 show_time()函数输出时间的值。#include using namespace std;
