Hello, this is one question and not multiple questions. Below is the question.

In C++, design and implement two classes in an inheritance hierarchy, according to the requirements listed below, and then demonstrate their capabilities through a short program.

Program Requirements:

Design a base class, Road, with the following members:

Attributes for storing the road’s name, number of lanes, and maximum speed limit.
A three-parameter constructor to initialize the three attributes.
Accessors and Mutators (Gets and Sets) for each attribute.
Input Validation: You should ensure that the number of lanes is always a value greater than 0, and that the maximum speed limit is a value between 0 and 100 MPH. This input validation should apply to both the 3-parameter constructor and the individual accessor functions.
A display function that prints the road’s information in a single line format (see the Sample Output for a formatting example).

b. Design a derived class, TollRoad, which inherits from Road. It should have the following members:

An attribute for storing the toll for using the road.
A 4-parameter constructor to initialize the three attributes of the base class, as well as the toll.
Accessor and Mutator methods for the toll.
Input Validation: You should ensure that the toll is a value greater than 0.0. This validation

should apply to both the 4-parameter constructor as well as the individual accessor.

An overridden display function that displays the information of the TollRoad in a two-line format, where the first line displays basic Road information, and a second line specifies

the current toll (see Sample Output for a formatting example).

C. In the main, you should demonstrate the capabilities of your classes by allowing the user to create new roads (or toll roads), as well as display a list of all previously created roads and their information (via their display function).

Your program should allow the user to add at least ten (10) Roads and/or TollRoads, which

should be represented in a single array. For an additional challenge, you may choose to remove that limit and support any number of roads, but this is not a requirement of the exam.
