C Programming Tutorial Part 1 - Compiling C using clang

Part 1 of our C Programming Tutorial covers the basics of compiling. What is a compiler? How does it work? How do I use a compiler to write programs in C? Every application that you write in C will have to be compiled. Furthermore, compilation errors and failures will be your first indication that you have made a mistake in your program somewhere. Understanding your compiler in and out will help you to write code much more efficiently.  For the purposes of our tutorial today, we will be discussing the clang compiler . clang is widely used - iOS developers should recognize it as the compiler used for developing iPhone apps as part of xCode and Apple's LLVM . I will also use a number of demonstrations; these demonstrations will include source code written in C, assembler and some garbage ASCII that is representative of machine code viewed through a text editor. For my part, I am using a Fedora Linux virtual machine for these demonstrations. That said, as I discussed initial
