string SetSpecies (string newSpecies){return newSpecies }
string GetSpecies (){species = newSpecies }
void SetSpecies (string newSpecies){return species }
string GetSpecies (){return species }
void SetSpecies (string newSpecies){ species = newSpecies}

15. (TCO 2) You have been tasked to create an EntertainmentSystem class and your boss wants you to consider the concept of encapsulation as you design your class. Which of the following actions will you take? (Points : 5)
Declare a single no-arg constructor in order to prevent outside entities from initializing the state of a new EntertainmentSystem object.
Combine attributes and behaviors specific to an EntertainmentSystem together into one cohesive unit.
Declare the class as static so that only one instance of an EntertainmentSystem can be used at a time.
Declare the class as private.
All of the above

1. Design a class named Fan to represent a fan. The class contains:

an int data field named speed that specifies the speed of the fan. A fan has three speeds indicated with a value 1, 2, 3.

A bool data field named on that specifies whether the fan is on.

A double data field named radius that specifies the radius of the fan.

A no-arg constructor that creates a default fan with speed = 1, on = false and radius = 10

The accessor and mutator functions for all the data fields.

NOTE: JUST CREATE fan.h and fan.cpp – no need to create the main.cpp – I just want to see the design of the class. (Points : 18)

2. Create a class called person that can hold a person’s name and age – also use dateType from class exercises to hold the person’s birthday in the person class.

Create the necessary attributes, accessor and mutator methods, a print function, and a constructor WITH arguments

Note: Create the class person.h and person.cpp only – you don’t need the main.cpp

Note: You do not need to include the dateType class in your answer just show me how you would use an object of the dateType class in your person class. (Points : 18)

3. Create a class called Child that inherits from the person class from the previous question.

Aside from entering a child’s name, age and bithday using the person class.

The Child class should allow for entering what grade the child is in and the child’s gender.

Create the necessary attributes, accessors, mutators, print function, and a constructor WITH arguments.

Note: Just create the child.h and child.cpp files, not the main.cpp (Points : 18)
3. Create a class called parent that inherits from the person class – aside from setting the adult’s name, age and birthday using the person class – you should also be able to set the parent’s occupation, spouse’s name, whether they are mom or dad, and the number of children they have.

Create the necessary attributes, accessors, mutators, print function, and a constructor WITH arguments.

Note: Create adult.h and adult.cpp only – not the main.cpp (Points : 18)

4. Create a class called simpleMath – this class should have two int attributes and accessor and mutator methods to set and get those two int attributes – and a calcSum method that returns the sum of the two ints, a calcDifference method that returns the difference of the two ints, a calcProduct method that returns the product of the two ints, and a calcDivision method that returns the division result of the two ints. Also make sure to create a constructor WITH arguments.

(The order of a/b or b/2 , a-b, b-a, is up to you)

Note: Just need to create the simpleMath.h and simpleMath.cpp files not main.cpp (Points : 18)

6. Create a class called Coin with one string attribute.

Create the proper accessor/mutator methods for the attribute.

Create a constructor that takes no arguments that sets the string to “Unknown”

Create a method that returns the numeric value of the coin string name.

For example:
.25 should be returned if the string attribute holds “Quarter”
.05 should be returned if the string attribute holds “Nickel”
etc.

Note: Just write out Coin.h and Coin.cpp – no need for main.cpp (Points : 18)

7. Put the person, child, and the parent classes together – keep in mind that person also has a composition with a dateType object. (You don’t need dateType.h and dateType.cpp in your answer here – but might need it if you want to compile this in visual studio)

Edit your classes –
1) Make the print function in the person class a pure virtual function – which makes person class an abstract class

2) Make the parent class also contain a child object array so that in the parent class you can not only put in how many children the parent has but that many array objects holding each of the child’s name, age, birthday, grade, and gender.

3) Edit the parent class print function so that it prints both the parent object information and the child information.

Create your void main –

In your void main create one dynamic instance of a parent object – and ask a user (assuming they are a parent) for their name, age, birthday, occupation, spouse’s name, whether they are mom or dad, number of children. Then for each children ask for the child’s name, age, birthday, grade, and gender.

Once you set all of this information for the dynamic parent object. Call the print function from the parent object so that it displays all of this information back to the user.

Note: Since I can see the classes from your previous answers – just paste in here the editted methods from the classes you made and the void main code. (Points : 22)
