最简单的模拟计时器：

#include<stdio.h>

#include<conio.h>

#include<windows.h>

int m=0,s=0,ms=0  //m是分 s是秒 ms是毫秒

//以下是5个自编函数

void csh( )  //初始化界面

void yinc(int x,int y)  //隐藏光标的函数(y值设为0就会隐藏)

void jishi( ) //计时器运行(每100毫秒变化一次)

void Color (short x, short y) //设定颜色的函数(y设为0就是黑底)

void gtxy (int x, int y) //控制光标位置的函数

int main(  )  //主函数

{  csh( )

   getch( )

   while(1)

       { jishi( )

       }

    return 0
