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<12)
    {
        printf("%02d:%02d:%02d AM
",hour,minute,second);
    }
    else
    {
        printf("%02d:%02d:%02d PM
",hour-12,minute,second);
    }
    return;
}

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

int main()
{
    MyTime one;
    one.SetTime();
    one.print_12();
    one.print_24();
    return 0;
}
