C语音简单计时器

#include<stdio.h>#include<time.h>#include<windows.h>int main(){printf("start...\n");int start = clock();int end ,time ,i = 0;while(1){//system("cls");printf("%d\r",i++);Sleep(1000);end = clock();time = (end - start)/CLOCKS_PER_SEC;if(time >= 5){printf("%d\n",i);break;}}printf("end...\n");return 0;}

利用clock()写的简单计时器，依次输出1到5，到达5秒自动退出
