Question

用C＋＋程序编写一套程序时钟设计

设计编写一个电子时钟类ElectronicClock，包括年 月 日 时 分 秒等属性，电子时钟类由时间类和日期类组合而成，实现并测试这个类。其中要完成的操作有：
1，构造函数
2，析构函数
3，对时间与日期进行校验的函数，当不正确时进行纠正与改错
4，对年，月，日，时，分，秒等属性性进行增加n个单位，注意不超出范围，进行进位

想要一套能在Microsoft Visual C＋＋中能运行的完整程序，各位大神拜托了

在判断年份上还有一些小BUG,(*^__^*)，请自行解决

写这个类还是比较容易的，不过也是要花时间。您的问题不像是在求助而是在提要求。那么你写这个类可能就得有点报酬了，哈哈
