Hi I'm a recent mac convert, and i need a little advice about programming languages for the mac. I've had light-moderate experience programming in Visual C and Visual Basic on the PC, and would be interested in continuing on the mac. What versions of C are available? Are there any freeware/open source C packages available? Does programming C on the mac differ that much from the PC? Does anyone know of any good sites that cater for mac programming, preferably with tutorials so i can get my footing again? Cheers in advance, and sorry for the noob-style question!
