Exercise - Failable Initializers

Exercise - Failable Initializers

Note: chosen language is "Swift"

Create a Computer struct with two properties, ram and yearManufactured, where both parameters are of type Int. Create a failable initializer that will only create an instance of Computer if ram is greater than 0, and if yearManufactured is greater than 1970, and less than 2017.

Create two instances of Computer? using the failable initializer. One instance should use values that will have a value within the optional, and the other should result in nil. Use if-let syntax to unwrap each of the Computer? objects and print the ram and yearManufactured if the optional contains a value.
