Answer 1

"ANSI C" doesn't know there is such a thing as "consoles" or "windows". This is almost certainly going to depend on the operating system and/or windowing environment being used, as well as any third-party libraries being used to drive these kinds of operations. Maybe something like ncurses would be helpful here, but there's no way of knowing without more specific information.

Answer 2

ANSI C doesn't have a concept of "windows". That's an operating system concept outside the area of the C language.

Answer 3

As people have mentioned, this doesn't make sense for ANSI C. For Windows, you'll need to be more specific about what you want.

If you're writing a console application (done automatically if you're using main , or if you explicitly pass the /SUBSYSTEM:CONSOLE flag to the linker), you don't need to do anything special. Running your application from a windowed application will spawn a console window for you. Running it from an existing console window will reuse that one.

If you're writing a windowed application (done automatically if you're using WinMain , or if you explicitly pass the /SUBSYSTEM:WINDOWS flag to the linker), you can use AllocConsole . See the Creation of a Console article from MSDN. (I think you also should be able to do that if you're writing a console application and never want to reuse an existing console, but I'd have to say that doing so would be very user-unfriendly.)

Answer 4

system("cmd");
