有人帮我看看如果要用C++改标准时间改怎么改吗

#include<stdio.h>
int main(){
int h,m,s;
scanf("%d",&s);
m=s/60;
h=s/3600;
printf("%02d:%02d:%02d\n", h, s, m);
return 0;
}

有帮助望采纳

#include <stdio.h>
int main()
{
    int h, m, s;
    scanf("%d", &s);
    m = s / 60 % 60;
    h = s / 3600;
    s = s % 60;
    printf("%02d:%02d:%02d\n", h, m, s);
    return 0;
}
