Скачать или смотреть Compiling C with XCode 4

This video shows how to open a XCode 4 project in order to compile a code written in C. When opening the project a sample code will appear on the file "Main.c", I did not modify this file, and it printed "Hello World!" on the screen (as it should have done).

Obviously if you want to write a larger code you can just open the file and drag it into the project folder.
This is useful mainly because it is very hard to find a C compiler for Mac, there is one made by Eclipse, but you have to install the library yourself, whereas after purchasing and installing XCode 4 you are ready to program in C.

I hope that it is clear enough, and one last thing: this is not supposed to be a C-Programming tutorial.
