                       At a Glance

                       A function is a set of steps that result in a single specific action.

                       Function parameters are the names listed in the function definition and Function arguments
                       are the real values passed to (and received by) the function.
                       The main purpose of using functions is to get rid of the repetitive block of code.
                       When an operation is performed inside a function it gives back a value, which can be used
                       later in the program to get the results, which makes a function more useful.
