Last CLASS method needs help... PAIR::area()

Sep 28th, 2006

Been working on this project for last 2 nights. Cant get rid of this error message on my last method PAIR::area() . It's defined at the bottom of my program.

Everything else compiles... builds... executes just fine. Rusty on the basics and trying to figure out methods.... here is my error message:

error C2601: 'area' : local function definitions are illegal
Error executing cl.exe.

It sounds obvious but I think I'm just a little blurry eyed. Project is due tonight (Thur) at 6pm. I think I need to go start at chapter one again It's has to be something dumb I'm doing.

Any help appreciated.

The things marked in red by me are the culprits. WHy dont u format the code properly so that typographic errors will be minimised. Do you write your code in Notepad. If so grab your self a syntax highlighter code editor which makes automatically proper indentations like Code::BLocks or Dev Bloodshed.

The links for the above IDE can be found at teh top of this forum in the thread named "Starting C".

Hope it helped, bye.

I don't accept change; I don't deserve to live.
