C 語言實例 C 語言實例

計算兩個時間段的差值。

實例

#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("輸入開始時間: \n"); printf("輸入小時、分鐘、秒："); scanf("%d %d %d", &startTime.hours, &startTime.minutes, &startTime.seconds); printf("輸入停止時間: \n"); printf("輸入小時、分鐘、秒: "); scanf("%d %d %d", &stopTime.hours, &stopTime.minutes, &stopTime.seconds); // 計算差值 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 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：

輸入開始時間: 
輸入小時、分鐘、秒：12 34 55
輸入停止時間: 
輸入小時、分鐘、秒: 8 12 5

差值: 12:34:55 - 8:12:5 = 4:22:50
