In this lesson you will learn what a compiler is and why you need one. You will learn a few things that you need to know first, and then you will write your first program: Hello World
C++ is case sensitive. That means that if the example uses the word "main" it must be typed exactly as shown. "Main", "MAIN" or any other change in the case is an error.
For the lessons on this website, we will be running the programs in a DOS window. We will not be creating a GUI, or graphical user interface.
