一个Time类，需要重载构造函数，并且进行加减运算，

Time.h：
#ifndef TIME_H
#define TIME_H
class Time
{
    int hour;
    int minute;
    int second;
public:
   
    ~Time(void);
    Time();
    Time(int,int,int);
    void init(int,int,int);
    void plus(Time& t);
    void minus(Time& t);
    void print_hms();
};
#endif;


Time.cpp:

#include "StdAfx.h"
#include "Time.h"
#include <iostream>
using namespace std;



Time::~Time(void)
{
}

Time::Time(int h,int m,int s)
{
    init(h,m,s);
}
Time::Time()
{
    hour=12;
    minute=30;
    second=30;
}
void Time::init(int h,int m,int s)
{
    second=s%60;
    minute=(m+s/60)%60;
    hour=(h+m/60)%24;
}
void Time::Plus(Time& t)
{
    hour=hour+t.hour;
    minute=minute+t.minute;
    second=second+t.second;
    init(hour,minute,second);
}
void Time::minus(Time& t)
{
    int sum=(second+60*minute+3600*hour)-(t.second+60*t.minute+3600*t.hour);
    second=sum%60;
    minute=(sum/60)%60;
    hour=(sum/3600)%24;
    init(hour,minute,second);
}
void Time::print_hms()
{
    cout<<hour<<"-"<<minute<<"-"<<second<<endl;
}


ttt2:

#include "stdafx.h"
#include <iostream>
#include "Time.h"
using namespace std;


int _tmain(int argc, _TCHAR* argv[])
{
    Time time1,time2(11,22,33);
    int h,m,s,h2,m2,s2;
    cout<<"按照时分秒输出：\n";
    time1.print_hms();
    time2.print_hms();
    cout<<"请输入时间（时、分、秒）：\n";
    cin>>h>>m>>s;
    time1.init(h,m,s);
    cout<<"请输入时间为：\n";
    cout<<"时分秒：";
    time1.print_hms();
    cout<<"请输入第二个时间：";
    cin>>h2>>m2>>s2;
    time2.init(h2,m2,s2);
    cout<<"请选择运算类型：";
    char i;
    cin>>i;
    cout<<"运算结果为：";
    switch(i)
    {
    case '+':
        {
            time1.plus(time2);
            time1.print_hms();
            break;
        }
    case '-':
        {
            time1.minus(time2);
            time1.print_hms();
            break;
        }
    default:
        cout<<"ERROR！！\n";
    }

    return 0;
}

下面是报错





各位大佬求助，怎么搞？？

我还是新手嘛，大佬这么打击我幼小的心灵··

不过，谢谢了
