How do you use the arrows in c?????
and can you press a key without having to press enter after it?????

How do you use the arrows in c?????
You use a platform-specific API. C has no notion of 'key', it only knows about files.

Linux: cbreak()
Win32: kbhit() and getch()
C doesn't really know how to do anything except mess with memory, in the plain language. All the various functions like printf() are part of a library called libc, but libc only gives you the very basics. For higher-level stuff like graphics and keyboard IO, you want to be using some API/library or another. Instead of piecing things together, you might want to look into a more general API like Win32 or SDL, or you might want to consider playing with a language that does do graphics and IO itself, like Java or C#.
