Question

HW_7d -   Cat class

Create 3 files:

1. Cat.h
   • Include a class specification for a Cat class
   • Data members include:
     • A cat’s weight
     • A cat’s color

• Member functions (methods) include:
  • A function called setWeight, to set the cat’s weight
  • A function called setColor, to set the cat’s color
  • A function called displayInfo, that displays a cat’s age and weight on the screen
  • A function called meow, that lets the cat say “Meow” on the screen

1. Cat.cpp
   • Include the method implementations for the four functions in this file

1. Source.cpp
   • Include main()
     • In main(), declare three cats (3 cat objects)
     • Name them: Fluffy, Tom, and Kitty

• Ask the user to describe Fluffy (get Fluffy’s weight and color)

• Fluffy (the Fluffy object) calls setWeight to pass the weight to the method, where

    the weight is assigned to Fluffy’s weight.

• Fluffy (the Fluffy object) calls setColor to pass the color to the method, where

    the color is assigned to Fluffy’s color

• Repeat the above for the Tom and Kitty objects.

• Have each of the Cat objects call the DisplayInfo method to output the age and color

   of each cat.

• Have each cat say “MEOW” on the screen by having each Cat object call the

     meow method.

/* OUTPUT:

So you have three cats...

Describe Fluffy. What does she weight? 4

What color is she? brown

Describe Tom. What does he weight? 9

What color is he? orange

Describe Kitty. What does she weight? 5

What color is she? white

Fluffy weights 4 pounds and is brown.

Tom weighs 9 pounds and is orange.

Kitty weighs 5 pounds and is white.

Fluffy says: MEOW!

Tom says: MEOW!

Kitty says: MEOW!
