结构体实现输入相应的秒数，计算得出新的时间（时钟）

输入开始时间： 

Please input hour-clock(12 25 20):  1 20 20
Please input seconds(1200):  10000

输出结果：

New Time : 04:07:00

#include <stdio.h>
#include <string.h>

typedef struct clock{
    int hour;
    int minute;
    int second;
}Clock;

int main()
{
    Clock clk;
    printf("Please input hour-clock(12 25 20):  ");
    scanf("%d %d %d", &clk.hour, &clk.minute, &clk.second);
    int seconds;
    printf("Please input seconds(1200):  ");
    scanf(" %d", &seconds);
    clk.second += seconds;

    while( clk.second>=60 ){
        clk.minute++;
        clk.second -= 60;
    }

    while( clk.minute>=60 ){
        clk.hour++;
        clk.minute -= 60;
    }

    while( clk.hour>=24 ){
        clk.hour -= 24;
    }

    printf("New Time : %02d:%02d:%02d", clk.hour, clk.minute, clk.second);

    return 0;
}
