Hi all, I've not posted for a while, been away at uni. Part of my course is called Software development for engineers, and this involves programming in C. basically we always include stdio.h as a library file but I don't seem to have this file on my mac. I have project builder and all the dev tools installed, but I just want to compile and run a simple C program like "hello world" the same way we do it at UNI with in the Turbo C IDE. If i copy the stdio.h header file to my mac and se it as an include, will gcc be able to compile code written at uni for my mac, and will I be able to do tasks on my mac that can be compiled and run on both the mac and the pc workstations at UNI? cheers for any help.
