经过测试，结果如下：
①
Enter the first time(hours minutes seconds):
2
34
45
Enter the second time(hours minutes seconds):
1
47
56
the result is:
4:22:41
press any key to continue...
②
Enter the first time(hours minutes seconds):
2
67
100
Enter the second time(hours minutes seconds):
1
56
200
the result is:
5:8:0
press any key to continue...
通过测试
