In this tutorial, we talked in depth about pre-processor commands and how you can define and undefine variables for in program use. We also talked about how you can use if statements in the pre-processor commands. After that, we talked about the basic syntax of a program. One thing I forgot to mention was that every line of code you write must be ended with a semi-colon. This is extremely important! your program will not compile without it and it can be extremely hard to find the mistake if you are not using visual studios.
