爱站程序员基地大学时期初学C++，做了些案例练习，想着整理一下，供自己和网友翻阅参考，谢谢支持！有个【模拟时钟系统】做的还可以。【PS】存在一些小问题，如编写习惯等，文末有简单小结，请自行辨析。算是提供不良模板，引以为戒
//**************************************************************************************//// 《简易时钟（C++）》(控制台程序) //// //// 注：还有很多小问题，如键入的域值、动态修改不灵敏、程序不稳定。。。 //// 还能扩充很多功能！ //// 可实现的功能： //// 1.能够手动初始化也能按照预设设置参数(可以设置两种时制！) //// 2.能够整点报时（用了windows API 函数）（在exe文件的所在目录里 //// 有相应的音频文件） （同时使用了蜂鸣进行模拟报时， //// 转义字符为‘\\a’） //// 3.能够随时暂停核相应继续时钟跳动 //// 4.可以重新设置参数 进行时钟运转，可以随时退出程序 //// 5.可以设置闹钟时刻，时刻一到，播放闹铃！ //// 6.可以切换两种显示方式 //// 作者：SHARP-EYE 2014.9.23 ////**************************************************************************************//

运行结果
运行起来的实际画面：
PS
功能挺多的，不过bug也挺多~~ 当年的野心还挺大，哈哈~
现在看来有很多低级错误和习惯问题，比如类成员变量没有前缀
m_
；方法名首字母没有大写，也没有依照匈牙利命名法和驼峰命名法；部分重复调用函数没有封装等等。
