Re: calculator clear code

One wonders how you managed to learn to put your post (unnecessarily) in bold, without learning to put the code in tags to preserve its formatting and make it stand out, or put it in the proper forum.

Re: calculator clear code

Re: calculator clear code

Well, this looks like Pascal, which I haven't touched in a couple of decades, or Delphi. I'm not sure why you posted it in the C++ forum.

Do you not know what language you're cutting and pasting? Have you been paying any attention in your classes, or what they are purporting to teach? Would you like me to move this to another forum, where you might find someone to tutor you?

Re: calculator clear code

why are you posting object pascal code?
