I am trying to learn to program in 'c'. Downloaded xcode development tools, installed those along with gcc compiler 3.3 and 4.0 When I try to compile a program that includes the statement #include <stdio.h> I get an error message, that it cannot find the file. Using terminal, and searching around, I navigated to /usr/include/gcc/darwin - there are 3 directories, 3.3, 3.3-fast, 4.0. These directories include various .h files such as stdint.h, etc. but no stdio.h - can anyone suggest what I should do next? Thanks!
