In this series, I want to introduce some concepts of the C programming language which I think is important.

In the first step, I will introduce how to compile a program and the workflow during compiling, because there are many useful options in the gcc no matter what you need to do that can bring some important prompts and features.

These tools must be installed

1. gcc (optional version, but not too old)
2. gdb (this is a useful debug tool)

Your operating system
OS (optional, Mac, Linux, Windows and so on)

We will see how to compile a program with some useful options tomorrow.
