/**Functions:
 *-	Functions return a value (using the keyword "return").
 * 
 *-	Functions that don't return a value are called subroutines (subs),
 * 	however they technically return a weird type called a void (holds no data)
 * 
 *-	In C++, functions are treated as variables in respect to their syntax.
