For learning, "C for Dummies".
For reference, "The C Programming Language".

>Is it really OK to program PICs in C language?

Yes.

>Or is it better to program PICs in assembly language?

Yes.

>What is the difference between C and C++?

Not gonna touch that one.

>Could PICs be programmed in C++?

Could they? Not really possible unless you created it yourself.

Maybe you should visit Shane Tolmie's web pages and get some sample code,
and go to Htsoft and get PICCLITE, and don't ever use printf() with a PIC.

Cheerful regards,
