You can use the preview button at the bottom to see how it looks.

Please post the actual error message and what IDE or compiler you are using.

It could be that something is not set up right.

Hello kannu,

After figuring out that your code is in three sections I was able to duplicate your error.

Some notes first:

In the header file

#include <iostream>
#include<string>

using namespace std;

The include files should not be here. Only in the ".cpp" files.

Line 4. Should not be used and never be in a header file.
http://www.lonecpluspluscoder.com/2012/09/22/i-dont-want-to-see-another-using-namespace-xxx-in-a-header-file-ever-again/
Good reading.

The ".cpp" file that goes with the header file is OK exept line 7 which is redundant do to that line being in the header file.

The actual problem comes from the "main" file what would be about line 4 #include "Source.cpp" . This includes the code from this file twice when you compile the program. It is a very rare occasion when you include a ".cpp" like this and not something you are ready for at this time. Otherwise you should never include a ".cpp" file in another ".cpp" file. After removing this line from main the program compiled with no linker errors.

I have not tested a run yet to see what happens, but it is a step in the right direction.

Hope that helps,

Andy
