Hi all;
I'm new to C++ and OOP.

My problem is:

I ' ve created the header file time1.h and included it in my project but when I tried to compile it gave me linker errors in VC++ 6.0.

Here is the code:

My header file time1.h

#ifndef TIME1_H
#define TIME1_H

class Time{

public :

    void SetTime(int,int,int);
    void showTime();

private :

    int second,minute,hour;




#include <iostream>
#include "time1.h"

using namespace std;

Time :: Time()
    second = minute = hour = 0;

void Time :: SetTime(int h,int m,int s)
    if((h >= 0 && h < 24) && (m >= 0 && m < 60) && (s >= 0 && s < 60))
        hour = h;
        minute = m;
        second = s;


        hour = minute = second = 0;

void Time :: showTime()
    cout<<(hour < 10 ? "0" : "")<<hour<<":"<<(minute < 10 ? "0" : "")<<minute<<":"<<(second < 10 ? "0" : "")<<second<<endl;

And my main.cpp

#include <iostream>
#include "time1.h"

using namespace std;

int main()

    Time time1,time2;





    return 0;


Here is the given errors :

In VC++

Cpp2.obj : error LNK2001: unresolved external symbol "public: void __thiscall Time::showTime(void)" (?showTime@Time@@QAEXXZ)
Cpp2.obj : error LNK2001: unresolved external symbol "public: void __thiscall Time::SetTime(int,int,int)" (?SetTime@Time@@QAEXHHH@Z)
Cpp2.obj : error LNK2001: unresolved external symbol "public: __thiscall Time::Time(void)" (??0Time@@QAE@XZ)
Debug/Cpp2.exe : fatal error LNK1120: 3 unresolved externals
Error executing link.exe.

Did you add time1.cpp to your project?

It compiled and linked ok for me with that compiler. Must be the way you set up the project. First, create a new empty console project. Copy the *.cpp and *.h files into the project folder, then use menu Project --> Add To Project --> Files, and select the files you added above.

Thanks for your helps...
I've solved the problem with your suggestions...

My problem was:

I've copied the three files in the same directory and tried to compile "main.cpp"

After I've added to these files in my project it worked...

Thanks again...
