毫秒级延时

#include<stdio.h>
#include<conio.h>
#include<time.h>
void delay (int i) //毫秒级延时
{
clock_t delay_;
delay_ = clock() + i * CLOCKS_PER_SEC / 1000;
while (clock() < delay_);
}
int main ()
{
unsigned int i;
while (1)//大循环
{
printf ("%d\n",i);
i++;
delay(100);
}
return 0;
}
开始学C/C++不久...这是用系统时间差来实现的
