I want to start developing using Xcode for OSX and I am 14 years of age,I am very computer literite. I am looking into buying a book that is very simple and will guide me through the whole process of knowing the C language,C language should be my best bet for OSX,some say try to use Cocoa but it is not really for beginners. I have found multiple books on Amazon.com such as C programming for Dummies,except how good would these be considering I am using a Unix based Machine and not DOS?What would be a good book for me to learn on a Mac and what are your suggestions? I was thinking finding a book,opening Xcode and go from there. It is very hard to find beginner guides to OSX programming so someone please help me out,I'm new. thanks a lot.
