Implement the following class MyPhoneBook. You can add additional private member variables and functions. The class has the following private member variables: 1- names and phones: Dynamic arrays of strings. 2- phoneBookSize: An int that holds size of phonebook. The Class has the following public/private member functions: 1- Parametrized Constructor that takes the size of PhoneBook and allocate dynamic arrays of names and phones and a copy constructor to initialize a PhoneBook using another PhoneBook. 2- A public function addEntry that adds a name and phone number at the first empty space at corresponding arrays, and returns true if entry is added, false otherwise. An entry is added if there’s space in the array and if phone number if valid. It checks for the validity of the phone number by ensuring that it has 11 digits, and doesn’t include any alphabets or special characters. 3- A public function displayEntryAtIndex(int) that displays a name and phone number at the specified index. It returns true if the index is in range, false otherwise. 4- A private function displayEntryAtIndices(int*) that receives an array of zeros and ones and has the same size of the class arrays. The function displays the name and phone number of an entry in the array only if the corresponding integer in the parameter array is one.

Implement the following class MyPhoneBook. You can add additional private member

variables and functions.

The class has the following private member variables:

1- names and phones: Dynamic arrays of strings.

2- phoneBookSize: An int that holds size of phonebook.

The Class has the following public/private member functions:

1- Parametrized Constructor that takes the size of PhoneBook and allocate dynamic arrays

of names and phones and a copy constructor to initialize a PhoneBook using another

PhoneBook.

2- A public function addEntry that adds a name and phone number at the first empty space

at corresponding arrays, and returns true if entry is added, false otherwise. An entry is

added if there’s space in the array and if phone number if valid. It checks for the validity

of the phone number by ensuring that it has 11 digits, and doesn’t include any alphabets

or special characters.

3- A public function displayEntryAtIndex(int) that displays a name and phone number at

the specified index. It returns true if the index is in range, false otherwise.

4- A private function displayEntryAtIndices(int*) that receives an array of zeros and ones

and has the same size of the class arrays. The function displays the name and phone

number of an entry in the array only if the corresponding integer in the parameter array

is one.

The array filled with values 0 or 1. Value O if name is not a match and 1 otherwise. 7- A public function findByPhone(string) that search in PhoneBook either by full phone number or a part of a phone number and returns an array of int with the same size of PhoneBook, The array is filled with values 0 or 1. Value 0 if phone number not a matc and 1 otherwise. 8- A public function updateNameAt(string,int) to update name in PhoneBook at specific index. It returns a bool which is true if the parameter index is within range and name is updated. 9- A public function updatePhoneAt(string,int) to update phone number in PhoneBook at specific index. It returns a bool which is true if the parameter index is within range and phone is updated. 10-A Destructor to deallocate dynamic arrays and leave no memory leak.
