在我电脑运行效果是06:59?

@[hope88888888](/user/576990) 是第9个测试点出错，难道是%.2d有问题吗？我看csdn上用c写这道题的是直接在printf函数里加上0的

@[dkp339](/user/1101832) 我少打了个0，抱歉
output
```
06:59
```
然后你没发现这个结果是错误的吗

```c
#include <stdio.h>
int main()
{
int s,v,at,H,T,t;
scanf("%d %d",&s,&v);
t = s/v;
if (s%v ==0)
at = t +10;
else
at = (t+1) + 10;
if (at<480)
{
H=(480-at)/60;
T=(480-at)%60;
printf("%.2d:%.2d\n",H,T);
}
else if (at == 480)
{
printf("00:00\n");
}
else if (at>480)
{
H=(1920-at)/60;
T=(1920-at)%60;
printf("%.2d:%.2d\n",H,T);
}
return 0;
}
``````
现在就好了

@[dkp339](/user/1101832) 祝贺
按照你的思路可以这样改
`t = s/v;`
-->
`t = (s - 1)/v;`
