This program named Average should use several functions to accept numbers from a user, then find the average of those numbers.

$$

Make sure your code implements the following functions:

$*$ main$()$: Controls the flow of the program

$*$ userInput$()$: Accepts nothing.$$ Returns one decimal value of the sum and one integer of the number of items. Accepts numbers from the user until they enter $0$ to quit. Adds the numbers together and keeps a count of how many user number entries there are.

$*$ average$()$: Accepts a decimal value and an integer $($in that order$).$ Finds the average of the decimal value, using the integer as the number of items. You cannot use the sum$()$ function.$$

$*$ userPrint$()$: Void function.$$ Accepts one decimal value and displays the average to two decimals.
