c++ - Multiple main CPP files in VisualStudio?

Question

I have a sample directory of some software, which contains multiple files with multiple main functions. May I assemble all of these files into single project, compile them and then run specific ones without getting main already defined error? Suppose I don't want to create separate project for each cpp file.

UPDATE

I need simple one-two-click solution (if it exists). I don't want to distribute files among folders or refactor files content. For example in Eclipse/Java you can right-click any file with main and run it. And there can be many of main files in one project. Is this possible for VisualStudio/CPP?

UPDATE 2

I know that C++ is not Java and that Visual Studio is not Eclipse. My question is about automation of some manual operations.

Answer 1

Put those main functions in separate namespaces and then define, which one do you want to run, eg.

File1.cpp

namespace F1
{
    int main(int argc, char * argv[])
    {
        // ...
    }
}

The-real-main.cpp

int main(int argc, char * argv[])
{
    if (whatever)
        return F1::main(argc, argv);
}

Edit: In response to additional information.

C++ is not Java and VS is not Eclipse :) The natural way to maintain multiple programs at once in VS is to put multiple projects (one for each executable or library) in a single solution. If you want to run a project, simply right-click it in Solution Explorer, select Set as Startup Project, and then click the Start button to run it.

To add a project to solution, right-click the solution and choose Add | New project... or Add | Existing project.
