Online compilers cannot implement this and can only be executed in software.
The software I use is: Visual Studio 2019
#include<stdio.h>
#include<Windows.h>
#include<time.h>
int main() {
for (int i = 0; i < 24; i++) {//控制小时
for (int j = 0; j < 60; j++) {//控制分钟
for (int k = 0; k < 60; k++) {//控制小时
printf("%d:%d:%d\n", i, j, k);
Sleep(1000);//休眠一秒继续执行程序
system("cls");//清屏
}
}
}
return 0;
}The effect is as follows:
