设计MyTime类 代码参考

 #include <iostream>
 #include <cstdio>

 using namespace std;

 class MyTime
 {
     private:
         int hour;
         int minute;
         int second;
     public:
         void SetTime(){cin>>hour>>minute>>second;return;}
         void print_12();
         void print_24();
 };

 void MyTime::print_12()
 {
     if(hour<)
     {
         printf("%02d:%02d:%02d AM\n",hour,minute,second);
     }
     else
     {
         printf("%02d:%02d:%02d PM\n",hour-,minute,second);
     }
     return;
 }

 void MyTime::print_24()
 {
     printf("%02d:%02d:%02d\n",hour,minute,second);
     return;
 }

 int main()
 {
     MyTime one;
     one.SetTime();
     one.print_12();
     one.print_24();
     return ;
 }
