Question

IN SWIFT LANGUAGE

In this lab we are going to create a game that uses all the different types of control flow operators that exist in SWIFT LANGUAGE.

The game will be a choose your own adventure game. The user will have to answer a series of questions and this will change the path of a story. This must be done by using if/else statements that are nested within other if/else statements. Your story must have four (4) different possible endings. Beyond this, you must provide some setup for the story to provide customized messages. Ask the user questions that will be used to capture details for use within the story.

Ask the user at least one question that has them choose something from a list of possible values and use a switch to set the appropriate variable.

Ask the user at least one question that results in a numeric range and use an interval switch to set another variable.

Also ask the user a binary (yes/no or true/false) question. Use the answer from this in a ternary to store another variable.

Use these variables within the output of the messages to the user in the story.

Example:

Example Program Output

Here is an example of a how the program might work...

Enter your favorite color?
Pick "red", "orange", "yellow", "green", or "blue"
> red

Do you like apples? "Yes" or "No"?
> Yes

How fast can you run a mile? Enter as a decimal number.
> 8.5

You are walking down the street eating some apples when a red tiger runs up and takes your lunch and then quickly runs away. 

Do you want to "chase" the tiger or "run away"?
> run away

You run away from the tiger but it is a bad idea to run from an animal. It turns and decides to try to eat you. You see a bus blocking your path up ahead. Do you "get on" the bus or "go around"?
> go around

There is a zoo keeper on the other side of the bus only to see a subway entrance. He captures the tiger and you are saved.

The End.

But then if you ran it again it might do this...

Enter your favorite color?
Pick "red", "orange", "yellow", "green", or "blue"
> green

Do you like apples? "Yes" or "No"?
> No

How fast can you run a mile? Enter as a decimal number.
> 20

You are walking down the street eating some oranges when a green tiger runs up and takes your lunch and then walks away.

Do you want to "chase" the tiger or "run away"?
> chase

The tiger runs but falls into the river. Do you "help it" or "leave it"?
> help it

You save the tiger and it is grateful. You have a new pet.

The End.
