$```$ Your Tasks

In this lab, you create a derived class from a base class, and then use the derived class in a C$++$ program. The program should create two Motorcycle objects, and then set the Motorcycle's speed, accelerate the Motorcycle object, and check its sidecar status. Use the Vehicle and Automobile classes that you worked with earlier in this chapter as a guide.

Instructions

Open the file named Motorcycle.cpp$.$ Create the Motorcycle class by deriving it from the Vehicle class. Use a public derivation

Task $1$: Create the Motorcycle class by deriving it from the Vehicle class. Use a public derivation.

In the Motorcycle class, create a private attribute named sidecar. The sidecar attribute should be data type bool.

Task $2$: Write a public set and get methods for the sidecar attribute. Task $3$: Write a public accelerate$()$ method. This method overrides the accelerate$()$ method inherited from the Vehicle class. Change the message in the accelerate$()$ method so the following is displayed when the Motorcycle tries to accelerate beyond its maximum speed:

"This motorcycle cannot go that fast".

In the MyMotorcycleClassProgram.cpp$,$ create two Motorcycle objects named motorcycleOne and motorcycleTwo. Set the sidecar value of motorcycleOne to true and the sidecar value of motorcycleTwo to false. Set motorcycleOne's maximum speed to $90$ and motorcycleTwo's maximum speed to $85.$ Set motorcycleOne's current speed to $65$ and motorcycleTwo's current speed to $60.$ Accelerate motorcycleOne by $30$ mph $,$ and accelerate motorcycleTwo by $20$ mph $.$ Print the current speed of motorcycleOne and motorcycleTwo.

Task $4$: Determine if motorcycleOne and motorcycleTwo have sidecars. If yes, display the following: "This motorcycle has a side car". If not, display the following: "This motorcycle does not have a side car".

An example of the program is shown below:

This motorcycle cannot go that fast

The current speed of motorcycleOne is $65$

The current speed of motorcycleTwo is $80$

This motorcycle has a side car

This motorcycle does not have a side car
