Question

5. Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close should be able to friends, and certain business associates. Your program handle a maximum of 500 entries. a. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables b. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapter's Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. c. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries e program should perform the following operations: i. Load the data into the address book from a disk. i. Sort the address book by last name ill. Search for a person by last name v. Print the address, phone number, and date of birth (if it exists) of a given person Print the names of the people whose birthdays are in a given month. vi. Print the names of all the people between two last names. vii. Depending on the user's request, print the names of all family members, friends, or business associates. C++using eclipse

Explanation / Answer

class personType
{
public:
void print() const;
//Function to output the first name and last name
//in the form of firstName lastName.

void setName(string first, string last);
//Function to set firstName and lastName according
//to the parameters.
//Postcondition: firstName = first; lastName = last

string getFirstName() const;
//Function to return the first name.
//Postcondition: The value of the data member firstName
// is returned.

string getLastName() const;
//Function to return the last name.
//Postcondition: The value of the data member lastName
// is returned.

personType(string first = "", string last ="");
//constructor
//Sets firstName and lastName according to the parameters.
//The default values of the parameters are empty strings.
//Postcondition: firstName = first; lastName = last

private:
string firstName;
string lastName;
};




class dateType
{
public:
void setDate (int month, int day, int year);
//Function to set date.
//The data members dMonth, dDay, and dYear are set
//according to the parameters.
//Postcondition: dMonth = monh; dDay = day;
// dYear = year

int getDay() const;
//Function to return the day.
//Postcondition: The value of dDay is returned.

int getMonth() const;
//Function to return the month.
//Postcondition: The value of dMonth is returned.

int getYear() const;
//Function to return the year.
//Postcondition: The value of dYear is returned.

void printDate() const;
//Function to output the date in the form mm-dd-yyyy.

dateType(int month = 1, int day = 1, int year = 1900);
//constructor to set the date
//The data members dMonth, dDay, and dYear are set
//according to the parameters.
//Postcondition: dMonth = month; dDay = day;
// dYear = year
//If no values are specified, the default values are
//used to intialize the data members.

private:
int dMonth; //variable to store the month
int dDay; //variable to store the day
int dYear; //variable to store the year
};
