Hey guys, this is bit of a noob question, but when working with VC++ 2008, how can you add several source files to a project and still be able to compile them all individually? My problem is that I am declaring the first file as the int main() but I don't know what to declare the other files so that I can compile them as well. (If I use int main() on the other files I get an error LNK2005: _main already defined in <filename>). Basically, what should I do to be able to compile them all. Also, they are not related, I am just going through exercises in a book and want to keep them organized.

Example:

#include <iostream>
using namespace std;
int main(){   
cout << "Get with the Program! \n";
return 0;
}

New, Separate File:

#include <iostream>
using namespace std;
int main(){				//What should I declare here so I can compile to test the code?
cout << "Having trouble! \n";
return 0;
}

Anybody understand what I'm asking? I feel like it is probably simple, but I can't find an answer on google.

Create separate projects. The idea of a project is that all files comprise one executable. If you want to organize several related binaries, create a solution and have multiple projects under that solution.

As the error says you are trying to build the project with two entry points( int main() 's) . In Visual C++ you can exclude a file from a build to do this right click it (in solution explorer) and click properties under general change exclude from build from no to yes.

I find it easier to create one project per executable. I think VS2008 does support multiple executables, DLLs etc in a single project but I haven't got a clue how. Also that way separate projects can be managed easily; once I've done with one I can delete or archive it without affecting anything else.

This might help though:

Yea, I started thinking about it a bit more and realized this. Thanks for clarifying. I was thinking more in terms of just separate files like in Dev C++ or something simpler. Thanks for the help.
