    Looks like you have set up your project as a Win32 Application. Create a new project and select Win32 Console Application instead this time. Then add your source file to this new project. When you create a Win32 Application, your linker is going to be looking for a WinMain function as a starting point in your code. If you select Win32 Console Application, then it looks for the main function as a starting point. You use Console Applications if you just need a quick and dirty interface to your program. The other one is for when you have more experience and want a windows interface with forms and buttons and menus and all that.

Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods."

    If you don't want to have to make a whole new project just because of that, there is a manual way to edit the settings:

    Go to the Project menu, then click Settings.
    Click the Link tab.
    Under project options you'll see a bunch of *.lib file names. After that should be "/nologo /subsystem:windows"
    Change this to "/subsystem:console"

    This tells the VC++ linker that you are not trying to make a normal windows application (which always contains WinMain, not main()) but a simple console application.
