Thread: Im having linking problems with turbo c++ ver 4.5

Background:
I am a newbie to programming.
I just started using this compiler, I used to use visual c++ .NET and I never had any linking problems there.

Problem:
I tried out with a simple program about a buffer and I got thease errors:

Code:

Linker Warning: No module definition file specified: using defaults
Linker Error: Undefined symbol Buffer::~Buffer() in Module Main.cpp
Linker Error: Undefined symbol Buffer::DisplayBuff() in Module Main.cpp
Linker Error: Undefined symbol  Buffer::ClearBuff() in Module Main.cpp
Linker Error: Undefined symbol Buffer::Buffer() in Module Main.cpp

Now here is the program:

Main.cpp

Code:

#include "Buffer.h"

int main()
{
	Buffer a;

	a.ClearBuff();
	a.DisplayBuff();

	return 0;
}

Buffer.h

Code:

#ifndef BUFFER_H
#define BUFFER_H

//class Buffer
class Buffer {
public:
	Buffer();
	~Buffer();

	void Add(int Pos, char *b);
	void ClearBuff();
	void DisplayBuff();

private:
	char *a;
};

#endif

Buffer.cpp

Code:

#include <iostream.h>
#include <string.h>
#include "Buffer.h"

Buffer::Buffer()
{
	a = new char[1999];
}

Buffer::~Buffer()
{
	delete[] a;
}

void Buffer::Add(int Pos, char *b)
{
	int i = 0;

	for (i = 0; i < strlen(b); i++)
	{
		if (Pos+i > 1999 || Pos+i < 0)
			return;
		a[Pos+i] = b[i];
	}
}

void Buffer::ClearBuff()
{
	int i = 0;

	for (i = 0; i < 1999; i++)
		a[i] == ' ';
}

void Buffer::DisplayBuff()
{
	int i = 0;

	for (i = 0; i < 1999; i++)
		cout << a[i];
}

Sorry for bothering you guys but I really would like to fix this problem. Thanks for any help.
