- CS 232 - Lab #6 - Pets Ahoy! We have recently been discussing the creation of classes in C++. Recall that classes serve as a "template" for the objects in our program, and that when we instantiate a class, we are creating an object which models the properties and behaviors of real-world objects. For this assignment, design and implement a parent class to represent a pet and several small sub-classes of the most common pets for cats, dogs, birds, and turtles. Each pet object is characterized by a type, name, birth date, owner, weight, sex, speak, and color. The variable data type for the type variable is a string that identifies the type of pet as a "dog", "cat", "bird", "turtle". The name is a string that identifies the name of the pet. The owner variable is a string that designates the name of the pet's owner. The weight specifies the pet's weight in pounds and is a double value. The speak variable is a string that holds an onomatopoeia of the sound the animal makes when it “speaks”…arrow_forwardi need the c++ codearrow_forwardAccomplish the following for the given class diagram.

- Implement the following hierarchy using C++ classes. 1. Shape: This should be an interface class that supports area() and display() functions. 2. Circle and Rectangle: Implement the area and display functions of Shape. 3. Quadrilateral: This class should be an abstract class. It may contain member variables for length and height. 4. Trapezoid: Should inherit length, height from Quadrilateral, and add 'side', represents the side parallel to 'length'. 5.

About: Chess is played on an 8 X 8 board where the initial placement of pieces. The white king is on e1, and the black king is on e8. Each chess piece can move in a specific way. Follow a simplified version. Most importantly, ignore an important rule in chess: Moving any piece in a way that puts your own king in check is illegal. Since we don't know what check means, for us a move is legal if the piece we are moving has an empty square to move to or can capture (replace) an opponent's piece (including their king). The king does not move at all. Nor can it castle the queen and knight can't move either. A pawn in the initial position may move one or two squares vertically forward to an empty square but cannot leap over any piece. Subsequently it can move only one square vertically forward…arrow_forward
