Write a program which allows the user to create a set of animals and to get information about those animals. Each animal has a name and can be either a cow, bird, or snake.
With each command, the user can either create a new animal of one of the three types, or the user can request information about an animal that he/she has already created. Each animal has a unique name, defined by the user.
Note that the user can define animals of a chosen type, but the types of animals are restricted to either cow, bird, or snake. The following table contains the three types of animals and their associated data.
| Animal | Food eaten | Locomtion method | Spoken sound |
|---|---|---|---|
| cow | grass | walk | moo |
| bird | worms | fly | peep |
| snake | mice | slither | hsss |
Your program should present the user with a prompt, >,
to indicate that the user can type a request.
Your program should accept one command at a time from the user,
print out a response, and print out a new prompt on a new line.
Your program should continue in this loop forever.
Every command from the user must be either a newanimal command or a query command.
Each newanimal command must be a single line containing three strings.
The first string is newanimal. The second string is an arbitrary string
which will be the name of the new animal. The third string is the type of the new animal,
either cow, bird, or snake. Your program should process each newanimal command
by creating the new animal and printing Created it! on the screen.
Each query command must be a single line containing 3 strings.
The first string is query. The second string is the name of the animal.
The third string is the name of the information requested about the animal,
either eat, move, or speak. Your program should process each query
command by printing out the requested data.
Define an interface type called Animal which describes the methods of an animal.
Specifically, the Animal interface should contain the methods Eat(), Move(), and Speak(),
which take no arguments and return no values.
- Eat() method should print the animal’s food,
- Move() method should print the animal’s locomotion,
- Speak() method should print the animal’s spoken sound.
Define three types
- Cow
- Bird
- Snake
For each of these three types, define methods
- Eat()
- Move()
- Speak()
so that the types Cow, Bird, and Snake all satisfy the Animal interface.
When the user creates an animal, create an object of the appropriate type. Your program should call the appropriate method when the user issues a query command.
