Where can I find a good (and easy to install) C++ compiler for mac?
It should already be on there. Open terminal, and enter "g++". If your terminal returns "error: no input files", then you already have it.
Mac has a free compiler called Code X.
I downloaded Code blocks and the Compiler isn't working. I did the Hello World code, and all it did was say some sort of error about the compiler.
I'm sure you will find it in the App Store using "Code X", but it's actually "XCode"
