计算两个时间段的差值。

实例

#include <stdio.h>

struct TIME

{

  int seconds;

  int minutes;

  int hours;

};

void differenceBetweenTimePeriod(struct TIME t1, struct TIME t2, struct TIME *diff);

int main()

{

    struct TIME startTime, stopTime, diff;

    printf("输入开始时间: \n");

    printf("输入小时、分钟、秒：");

    scanf("%d %d %d", &startTime.hours, &startTime.minutes, &startTime.seconds);

    printf("输入停止时间: \n");

    printf("输入小时、分钟、秒: ");

    scanf("%d %d %d", &stopTime.hours, &stopTime.minutes, &stopTime.seconds);

    // 计算差值

    differenceBetweenTimePeriod(startTime, stopTime, &diff);

    printf("\n差值: %d:%d:%d - ", startTime.hours, startTime.minutes, startTime.seconds);

    printf("%d:%d:%d ", stopTime.hours, stopTime.minutes, stopTime.seconds);

    printf("= %d:%d:%d\n", diff.hours, diff.minutes, diff.seconds);

    return ;

}

void differenceBetweenTimePeriod(struct TIME start, struct TIME stop, struct TIME *diff)

{

    if(stop.seconds > start.seconds){

        --start.minutes;

        start.seconds += ;

    }

    diff->seconds = start.seconds - stop.seconds;

    if(stop.minutes > start.minutes){

        --start.hours;

        start.minutes += ;

    }

    diff->minutes = start.minutes - stop.minutes;

    diff->hours = start.hours - stop.hours;

}

输出结果为：

输入开始时间:

输入小时、分钟、秒：

输入停止时间:

输入小时、分钟、秒:   

差值: :: - :: = ::
