Array	An ordered collection of items denoted by `[]`. For example: `string[] names = new string[] { "Mark", "Paula", "Sandy" , "Bill" };`
List	An ordered collection of items denoted by `new List<VariableType>()`. Lists are more flexible than Arrays and can be altered. For example: `var names = new List<string>() { "Mark", "Paula", "Sandy" , "Bill" };`
Getting Specific Elements from an Array or List	To access a specific element within a List or Array use the `[]`. For example: `var firstName = names[0];`
`names.Count;`	The `.Count` property counts the amount of items within a list.
`names.Add();`	The `.Add()` method adds a variable of the same data type to the list.
