Methods (Functions)

Here are some of the reasons methods are useful: 

. By giving a name to a sequence of statements, you make your program easier to read and debug. 

. Dividing a long program into methods allows you to separate parts of the program, debug them in isolation, and then compose them into a whole. 

. Methods facilitate both recursion and iteration. 

. Well-designed methods are often useful for many programs. Once you write and debug one, you can reuse it.
