So I am a new programmer and I just installed XCode on my Macbook to get the GCC. I think Xcode is the only way for getting GCC on OSX. Now when I run my Hello World application, in C++, g++ comes up saying it is version 4.0.1 but when I look for commands starting with g I also see g++-4.2. Is there any way of making 4.2 default rather than 4.0.1, and also is there a way to updating gcc to the latest version 4.4.0?

EDIT: Ok, so I installed macports and installed gcc4.4 and it shows up on terminal as gcc-mp-4.4 and how do I make it default with gcc_select, like what are the commands and stuff. Thanks.

If you install macports you can install gcc select, and then choose your gcc version.

/opt/local/bin/port install gcc_select

To see your versions use

port select --list gcc

To select a version use 

sudo port select --set gcc gcc40
