question says it all. (I reserved 2 library books which came on the same day. I saw them on the shelf and realized that they were the same except one was ObjC and one was ObjC 2.0. (not full titles...)
Bonus, what is Objective C++? objectie

A little wiki told me:
- Objective-C: a C-style programming language with Smalltalk-style messaging.
- Objective-C++: a GCC front-end which adds to C++ the extensions Objective-C adds to C.
- Objective-C 2.0: a revision of the Objective-C language that includes modern garbage collection, syntax enhancements, runtime performance improvements and 64-bit support. Also adds features such as properties and fast enumerators. Currently only for OSX.

Apple has an overview of Objective-C 2.0 on its Web site, though it's worth noting that the version of Objective-C 2 on the iPhone doesn't include garbage collection. Basically, the differences amount to:
- Garbage collection (on the Mac)
for (id object in collection)- Properties and dot-syntax
- Changes to the low-level runtime functions
Objective-C++ is a compiler mode that allows you to intermingle C++ code with Objective-C code in the same function body.
