CSI 2372-Assignment 3 Solved

Question 1 of 2) Person and Organization Class need to create 2 classes: Person (represents a person) and Organization (represents an organization).

People can join an organization, and each organization must maintain a table of all registered members.

The Person class has two private members: The person's name and age. (You can give default values for name and age)

You must create public access methods for these 2 members.

The Organization class has these private members: class Organization { 

name: the name of the organization (you can give a default value for name)
 members: a pointer to an array of Persons
size: the actual size of the members array (the actual number of people in the organization)
dim: the maximum size of the members array (the maximum number of people the organization can have). The default size of an organization is 100 Persons.

 The Organization class has a public method to return the list of members of the organization:

The Organization class also has another public method to add a person to the array of members of the organization (We double the max size of the array if the array is full):

Note: the array of members of an Organization must be dynamic, so be sure to add the necessary methods for properly managing dynamic memory (constructors, destructors etc...) 

You provide at the end a global void function to implement (printMembers()) to display the members of an organization at std::cout:

At the end, you are given a main() program to test your classes.

You can't modify the principal program, so make sure you don't get any runtime or compilation errors. 

Question 2 of 2) Inheritance (Specialization, Generalization)

We will take the Organization and Person classes from Question 1 and add a sub-class and some dependencies to them. The main() code file is available in the BS.  
First, you need to add an array of pointers to organizations in the Person class. 

    Organization** organizations; 

 A person can be member of at most 5 organizations (fixed size array), so organizations attribute is a pointer to a dynamic array of type Organization * and size 5. If we try to add a 6th organization, then an exception std::out_of_range is thrown. The constructor of Person class is a good function to to this initialization.

The registering non-member function that will allow to add an organization to a person and a person to an organization with the following format:  
//add a person to an organization and an organization to a person   void registering(Organization* o, Person* p) // two lines of code 

 The addPerson function has already been implemented in Question1, so for the registering function you need to call addPerson in the Organization class and you have to call the addOrganization function in the Person clasvoid Person::addOrganization(Organization* organization)  

// adds a Person to the members array of the organization // Should double the members array size if array is full  void Organization::addPerson(Person person) 

  Then, you must add a sub-class of Organization called University which will have an attribute tuition (float) that you can access with getTuition() and setTuition().  

The getOrgNames() of Class Person returns a string of all the organizations of the person.
//returns a string containing all the organizations (org and univ) of the person std::string Person::getOrgNames()

Add a method getTotalTuition() method in the Person class that will sum the Tuition for universities that a person is registered. Some Person class member function prototypes: float Person::getTotalTuition() 
//returns a string containing all the universities of the person 
      std::string Person::printSchools()   

You have to loop through the organizations, do a downcast (with dynamic_cast)  in order to check which elements that are pointed by the organizations are University objects and sum up the results of getTuition(). The pointers in this dynamic array are accessible by [].

dynamic_cast allows you to determine if a pointer is pointing to a derived class (University) or to a base class (Organization), which is specified by the return value of dynamic_cast.   

Add the ordinary non-member function printMembers function that prints the name of the person, the number of organizations the person belongs to and the set of organizations the person belongs to.
