Hi there, this is my first post here although I have lurked here for a while. I also apologise for asking something that probably has dome before. My background is a physics masters and I am familiar with Fortran 95 and extensively used Matlab (well gnu Octave) on my 10 month placement. I am looking to learn c++ for when I start my PhD as I'll need to do a lot of data analysis and it seems it's the language others in the group use. My question is, what do I need to get going with c++ on a mac. I have Xcode as I got it by mistake over a year ago, but do I need anything else to begin my "hello world" program? Are there any useful websites or books? Thanks in advance.
