/* Getting started with linux.

Figure out what directory you're in:
    -   pwd

List content of current directory. Think "List":
    -   ls

Get more information with a flag. Think "List Long":
    -   ls -l

/*
C Programming is a compiled language
    This means that all syntax has to be legal in order to create an executable file
C is one of the oldest languages still used today
    Inspired numerous other languages (C++, C#, Java, etc)
C is not object oriented
C is statically typed (all variables are given a type at compile time)
C is not forgiving - Simple mistakes are not told to you
C is dangerous but helps you learn the details and behind the scenes
C is valuable - Still in demand, foundational concepts help everyone
