Overview

This lab will give you practice writing functions that incorporate math, booleans, conditional, and swift statements.

##Instructions In this final lab you'll be writing three functions. All of your functions should be written in the ViewController.swift file located in the .xcworkspace file (included with this repo.).

1 - Create a function named averageIsAbove75 that takes in three arguments with the type Double and a return type of Bool. It should take these three values and find their average. If the average is greater than 75.0, then return true, else return false.

If you were to call on this function, it would yield the following results. Notice how there are no external names to the parameters when this function is called.

averageIsAbove75(55, 25, 24)
// false

averageIsAbove75(100, 85, 90)
// true

2 - Create a function named passwordCombo that takes in two arguments, one of type String which represents the username and the other of type Int which represents the password. This function will return a String letting the caller of this function know if the username/password combo passed into the function is correct!

What makes it correct? The conditions are.. the username String must be either 'Jerry', 'Elaine', or 'Michael'. The password must be divisible by 3. If the username + password conditions pass, then return back the String "Welcome!". If either fail, then the String to be returned should be "Access Denied"

Calling this function should yield the following results. Notice the external names of these arguments when calling on this function.

passwordCombo(username: "Bran", password: 22)
// "Access Denied

passwordCombo(username: "Elaine", password: 20)
// "Access Denied"

passwordCombo(username: "Elaine", password: 33)
// "Welcome!"

3 - Create the function describe(emoji:). It should take in one argument of type String and return back a String.

You should switch on the emoji argument in your implementation and return back a String describing the emoji that is passed in as an argument. The emoji's and their descriptions you should include in your switch statement are the following:

💋 - "Kiss"
🐈 - "Cat"
🐢 - "Turtle"
🍕 - "Pizza"
👻 - "Ghost"

For the default case, we should return back the String "Unknown".
