PAT乙级 程序运行时间(15)

注意控制一下时间格式就ok,就是1一定要输出01,0一定要输出00.

#include "iostream"
#include "stdio.h"
#include "string"
#include "string.h"
#include "map"
using namespace std;

int main()
{
long c1,c2;
cin>>c1>>c2;

c1 = c2-c1;
if(c1%100>=50)
c1 = c1/100 + 1;
else
c1 = c1/100;

int hour,min,sec;
hour = c1/3600;
min = (c1%3600)/60;
sec = c1%60;

printf("%02d:%02d:%02d\n",hour,min,sec);

return 0;
}
