Preprocessor Directive The preprocessor directive is a command that allows us to use codes that other people have written.
Main Function The main function dictates how the code will run. It includes expression and declaration statements.
Expression Statement Expression statements are words that are displayed to the end user.
Declaration Statement Declaration statements name and define variables.
Return Statement I’m not 100 % sure what the return statement does, but I think that the return statement closes out the code in the main function and allows it to be compiled.
