3 Methods will be created

One that asks for and returns the first name of the current user being created (should take 0 arguments)

One that asks for and returns the last name of the current user being created (should take 0 arguments)

One that takes the current first and last name, and combines them into a logon name (should take 2 string arguments)

Heres the steps:

Call a method that will ask for the new users first name. Have it return that name as a string

Call a method that will ask for the new users last name. Have it return that name as a string

Call a method that will combine the first and last name into a username. The first and last name are this methods arguments. Return the string result.

For example, Sue + Baker will return SueBaker.

Output the result in a statement that uses the first name, last name, and user name.
