Question

c++设计时钟类,数据成员有时，分，秒，函数成员可实现修改时钟时间，显示时钟时间，

其他要求：
1，构造函数重载；
2，有形参缺省值；
3，有析构函数；
4 有内联函数；
5 有主函数

以前linux系统下写的...windows下好像c++没有sleep函数，要引用下windows.h吧！

追问

程序有错误

追答

是的 把windows.h头文件去掉就可以在linux编译通过的，但windows下好像只有加windows.h
才能用sleep，然后我就加了试试，发的时候忘删除了
如果不是这个问题...那就算了，你觉得有用就看看，别用就当我没回答过，无视我就行...刚学c++的时候写的 ，不想重看了

代码基本符合要求 但是还是不行 运行结果显示为静态 要能要像电子表一样显示 请改进一下
