1026. 程序运行时间(15)

原题: https://www.patest.cn/contests/pat-b-practise/1026

实现思路: 就是转换输入格式的问题, 给秒转成"时分秒"显示格式.

完整代码:

#include <stdio.h>

int main (void) {
float CLK_TCK = 100.0;
int c1;
int c2;
int source;
int h = 0;
int m = 0;
int s = 0;

scanf("%d %d", &c1, &c2);
source = (int)((c2 - c1) / CLK_TCK + 0.5);
h = source / 3600;
m = (source - h * 3600) / 60;
s = source - h * 3600 - m * 60;
printf("%02d:%02d:%02d\n", h, m, s);

return 0;
}
