C 語(yǔ)言實(shí)例 - 計(jì)算兩個(gè)時(shí)間段的差值
C 語(yǔ)言實(shí)例計(jì)算兩個(gè)時(shí)間段的差值。
實(shí)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("輸入開(kāi)始時(shí)間: n");
printf("輸入小時(shí)、分鐘、秒：");
scanf("%d %d %d", &startTime.hours, &startTime.minutes, &startTime.seconds);
printf("輸入停止時(shí)間: n");
printf("輸入小時(shí)、分鐘、秒: ");
scanf("%d %d %d", &stopTime.hours, &stopTime.minutes, &stopTime.seconds);
// 計(jì)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:%dn", diff.hours, diff.minutes, diff.seconds);
return 0;
}
void differenceBetweenTimePeriod(struct TIME start, struct TIME stop, struct TIME *diff)
{
if(stop.seconds > start.seconds){
--start.minutes;
start.seconds += 60;
}
diff->seconds = start.seconds - stop.seconds;
if(stop.minutes > start.minutes){
--start.hours;
start.minutes += 60;
}
diff->minutes = start.minutes - stop.minutes;
diff->hours = start.hours - stop.hours;
}
輸出結(jié)果為：
輸入開(kāi)始時(shí)間: 輸入小時(shí)、分鐘、秒：12 34 55 輸入停止時(shí)間: 輸入小時(shí)、分鐘、秒: 8 12 5 差值: 12:34:55 - 8:12:5 = 4:22:50其他擴(kuò)展
