Question

!求教啊c/C++的电子时钟课程设计。要求：1具有闹钟功能，2通过键盘可设置年月日时分秒，3具有整点报时功能

4要求程序运行稳定可靠。（不是MFC的，仅仅只是初级C++的程序代码C++SOURCE，也不是单片机什么的）。 （下面是一个大概程序，但是功能不全，屏幕上没有数字时钟显示，不能设置时分秒。不用同步本地时间，要自己设置的那种。可以根据以下程序做修改补充，也可以帮忙重新编写一个，，谢谢啦！！！！）
#include <windows.h>
#include <iostream>
#include <ctime>
using namespace std;
//-----------------------------------------------------------------------------
// 互斥量用于避免线程之间文字输出交叉
// 本程序中仅对重要的地方做了保护

// 主菜单
void mainMenu()
{
int op = 10;
while (op != 0) {
LockOut();
cout << endl
<< "请选择功能:" << endl
<< "1. 打开整点报时" << endl
<< "2. 关闭整点报时" << endl
<< "3. 设置闹钟" << endl
<< "4. 打开闹钟" << endl
<< "5. 关闭闹钟" << endl
<< "6. 打开秒表" << endl
<< "0. 退出" << endl << endl;
