First class challenge here. I will take a shot and say that the main () function is the base set of rules that will allow the program to execute properly by using the if and when statements
Preprocessing Directives- These are going to instruct the compiler to pull data from a header file
Main Function - Where the body of all the code lives and what you will be executing upon receiving a return statement
Expression Statements - these are any line of code that end with a semi colon that is not declaring something
Decleration Statements - declaring a value or a constant in a line of code
