I am learning now c++. In PC in our university we program with DevC++ and Turbo C++ in which we are able to see the available headers and their contents and a brief explanation of what each function included in a header (for example stdio.h) does. But in OS X many things change with in the headers. And I want to be able somehow to view the available ones, and view the functions contained therein. How can I do that, preferably in xCode? Thank you in advance.
