In a previous project, I created an address book that utilized a Vector Class.

This week, I must modify the Vector address book program by creating:

1. Person Class

2. Employer Class

3. Personal Info Class

These classes must utilize a HAS-A Relationship

Then, I must use the Employer and Personal Info classes as member variables of the Person class.

Modify the Vector class to hold People objects instead of Record objects.

Modify the menu interface and input algorithms to accept data for the Employer and Personal Info classes via functions in the Person class.

Modify the Output to print all the information in each Person object, associated Employer object, and associated Personal Info object.

Make sure to separate the implementation of classes from the header files.

Have a .cpp file and a .h file for each class I create.

 

Here is the code from the Vector Address Book that must be modified. It has a main.cpp, Record.h, Record.cpp, VectorClass.h, and VecotrClass.cpp:

 

/*main.cpp*/

/***** main.cpp *****/
#include
#include "Record.h"
#include "VectorClass.h"
using namespace std;
int main() {
   VectorClass recVector;
   int op, age, telephone;
   string firstName, lastName;
   while (1) {
       cout << "1. Input information into a record." << endl;
       cout << "2. Display all information in all records." << endl;
       cout << "3. Exit the program" << endl;
       cout << "Enter option: ";
       cin >> op;
       switch (op) {
           case 1:
               try {
                   cout << "Enter first name: ";
                   cin >> firstName;
                   cout << "Enter last name: ";
                   cin >> lastName;
                   cout << "Enter age: ";
                   cin >> age;
                   cout << "Enter telephone number: ";
                   cin >> telephone;
                   Record newRecord(recVector.size() + 1, firstName, lastName, age, telephone);
                   recVector.push_back(newRecord);
               } catch (const exception& e) {
                   cerr << "Error: " << e.what() << endl;
               }
               break;
           case 2:
               cout << "Record Number FirstName LastName Age Telephone-Number" << endl;
               cout << "-----------------------------------------------------" << endl;
               for (int i = 0; i < recVector.size(); i++) {
                   recVector[i].print();
               }
               break;
           case 3:
               cout << "Exit the program." << endl;
               return 0;
       }
       cout << endl;
   }
}
