Simple console approach for Windows:

using Visual Studio, create a console app project - the entry point with be _tmain(...). The app will open in a console window. "#include <iostream>" will provide std::cout and std::cin. You can use std::cout << "Some debug info: " << some_debug_value << "\n"; as desired.

From _tmain, call your app starting point.

assuming visual studio, open the project property pages. linker-->system-->subsystem. Choose console and add a main() entry point for the program.

int main( void ){

//good enough

}

how did you create the empty project though? Looks like you have to pick windows,console, dll, or static lib when you create a new project.

I'm trying to add a Console to an existing project, not start a new Console Window Project.

You're providing no information on what IDE you're using, what operating system, etc. Both jms bc and I are just making guesses. It sounds like you might be using Visual Studio and Win32. If you want more specific answers, provide some specific information - what IDE? what version? what API?

Looks like you're probably looking for the

AllocConsole function to add a console to a window'd project.
