Functions

__**Functions**__ Typing the same code over and over again can be boring and time consuming so insed of repeating some not so important lines of code that are the same on a diffident programs. programmers use functions.

Functions are reusable pieces of code in an programs. They save the programmer coding time by providing a way to perform the  same process by simply calling the function, passing a variable, and returning a value. You can create functions as part of a  separate class, or the function can be private and reusable only within the current class.
