请记住，您可以将小时/分钟/秒的整数值转换为单个整数，如下所示：

int totalSeconds = ((hours * 60) + minutes) * 60 + seconds;

并转换回：

int hours = totalSeconds / 3600;  // Be sure to use integer arithmetic
int minutes = ((totalSeconds) / 60) % 60;
int seconds = totalSeconds % 60;

或者，您可以按以下步骤进行算术零碎：

int totalHours = hours1 + hours2;
int totalMinutes = minutes1 + minutes2;
int totalSeconds = seconds1 + seconds2;
if (totalSeconds >= 60) {
  totalMinutes ++;
  totalSeconds = totalSeconds % 60;
}
if (totalMinutes >= 60) {
  totalHours ++;
  totalMinutes = totalMinutes % 60;
}
