All right on to the suparameter.

Did you know that each of the suits is included in Unicode?

Meaning that each suit is a character that we can type out.

Let's start by replacing our suit and

our print string with a dollar sign and then brackets.

Inside the brackets, let's call a function that doesn't exist yet

named getSuitChar and pass in the suit.

Then let's use Alt+Enter to create the function.

And after it's created, let's delete the brackets and

then set this function equal to when suit and then add brackets.

And inside our when statement,

let's start by checking if the suit is equal to diamonds.

And if it is, Then let's return the Unicode

character for diamonds, which is \u2666.

Next hit command or Ctrl+D three times to duplicate this line.

And then let's change these extra

diamonds to clubs, hearts and spades.

And let's change the Unicode characters to u2663 for

clubs, u2665 for hearts and u2660 for

spades, these are all in the teacher's notes as well.

Finally, since we're counting on this when statement to always return something

let's add an else.

And if we get anything else,

let's return a string that says incorrect suit then let's run the app.

And sweet, I got the ten of spades.

My favorite.

Last but not least, let's deal with the face up property.

If a card is face up, we should be able to see it.

But if it's face down, we shouldn't be able to tell what card it is.

So really, I shouldn't be able to tell that this card is a ten of spades.

To fix this, let's first take the face up property out of our print string.

Then let's add a line above the return and type if faceUp.

And then put our return statement inside the brackets.

Next let's add an else and if it's not face up, let's return three Xs.

Great, but before we move on, let's make this two string function a lot smaller.

To do that, I first need to tell you about the ternary operator and column.

Remember the Ternary Operator?

It's these guys.

They let us do a conditional statement on only one line.

See, the thing is, Kotlin doesn't have a Ternary Operator.

Instead, with Kotlin, an if statement returns a value.

So instead of using some weird syntax, we can just use if and

else like we're used to.

So to get this down to one line,

let's first delete the outside brackets and then add an equal sign.

Then, since if statements already return values, let's delete the return keywords.

And finally, let's get rid of the brackets and put everything on one line.

Awesome, our two string function is ready for action.

Now let's give it some exercise by printing out the entire game board instead

of just the top card in our deck.
