I need help with creating a project that if the given radius of a circle returns , the area using the formula PI*^2. Create a header file, an implementation file and a driver program . Can anyone help me ??

Well can you manage to do it all in one file, before adding to the complication (slightly) by making it 3 files?

Or are you perhaps thinking that ^ is "raise power", and wondering about some strange error messages in the code you have?

it should read formula PI*r^2

cant you use math.h ?
