In object oriented programming, inheritance improves code readability and maintenance by allowing new classes to re-use existing classes. Use inheritance to solve the following problem: A: A Car is a Vehicle and has a name, a max_speed value and a number_of_cylinders attribute that specifies the number of cylinders in the car's engine. - Add accessor and mutator methods to get and set the values of the class attributes. - Attributes of the car objects are initialized at the time when the object is created. - When a car object is printed, its name, max_speed and number_of_cylinders are shown. B: An Airplane is also a Vehicle and has a name, a max_speed value and a number_of_engines attribute that specifies the number of jet engines the airplane has. - Add accessor and mutator methods to get and set the values of the class attributes. - Attributes of the airplane objects are initialized at the time when the object is created. - When an airplane object is printed, its name, max_speed and number_of_engines are shown. C: When an instance of a Vehicle object is printed, its name, max_speed are shown. Please note that Vehicle class should have its own_str_ method and Car and Airplane classes should override it. D: Write a test program that creates an instance of the Car class, an instance of the Airplane class and performs the following operations: - Calls all accessor methods of the car and airplane objects and prints their results. - Increases the max_speed of the car object by 200 and the max_speed of the airplane object by 500 - Prints the car and the airplane objects. - Compares the speed of car and airplane objects and prints a message that identifies the one that goes faster.

In object oriented programming, inheritance improves code readability and maintenance by allowing new classes to re-use
existing classes. Use inheritance to solve the following problem:
A: A Car is a Vehicle and has a name, a max_speed value and a number_of_cylinders attribute that specifies the number of cylinders in
the car's engine.
- Add accessor and mutator methods to get and set the values of the class attributes.
- Attributes of the car objects are initialized at the time when the object is created.
- When a car object is printed, its name, max_speed and number_of_cylinders are shown.
B: An Airplane is also a Vehicle and has a name, a max_speed value and a number_of engines attribute that specifies the number of jet
engines the airplane has.
- Add accessor and mutator methods to get and set the values of the class attributes.
- Attributes of the airplane objects are initialized at the time when the object is created.
- When an airplane object is printed, its name, max_speed and number_of_engines are shown.
C: When an instance of a Vehicle object is printed, its name, max_speed are shown. Please note that Vehicle class should have its
own_str
method and car and Airplane classes should override it.
D: Write a test program that creates an instance of the Car class, an instance of the Airplane class and performs the following
operations:
- Calls all accessor methods of the car and airplane objects and prints their results.
- Increases the max_speed of the car object by 200 and the max_speed of the airplane object by 500
- Prints the car and the airplane objects.
- Compares the speed of car and airplane objects and prints a message that identifies the one that goes faster.
- Please note that your solution should use inheritance to avoid duplicate code.
