Hi I need help with this, here are the insctructions.
*****Instructions*********
you will be creating a class definition for a Contact, like one that you would add to your phone. Each Contact will have a first name, last name, phone number, and email. Within the class definition, there will be an accessor and mutator function for each member variable. Also, inputContact and displayContact. Main will behave like the previous homework assignment, which will be a menu based program that will display options to add a new contact, display all contacts, search for a contact by first name, and exit.
Contact
Member Variables
cstring member variables for first name, last name, phone number, and email. Each of these member variables will be private and have a static size of 32.
public member functions
Each member function will be declared (prototype) within the class definition and defined outside the class definition (scopeResolution::operator)
bool setFirstName - this function will pass in a const cstring and assign the passed parameter to the first name member variable and return true
bool setLastName - this function will pass in a const cstring and assign the passed parameter to the last name member variable and return true
bool setPhoneNumber - this function will pass in a const cstring and assign the passed parameter to the phone number member variable and return true
bool setEmail - this function will pass in a const cstring and assign the passed parameter to the email member variable and return true
char* getFirstName - this function will return the cstring member variable first name
char* getLastName - this function will return the cstring member variable last name
char* getPhoneNumber - this function will return the cstring member variable phone number
char* getEmail - this function will return the cstring member variable email
void inputContact - this function will create a cstring called temp with static size 32. For each member variable, prompt the user for input and call the corresponding mutator function passing the temp cstring
void displayContact - this function will print each member variable of the Contact calling the corresponding accessor function.
Default Constructor
The default constructor will initialize the each cstring member variable to an empty string. The definition will be outside the class definition
Destructor
The destructor will assign \'\\0\' to the first subscript of each member variable. The definition will be outside the class definition
Global Functions
void addContact - this function will pass an array of Contact Objects and an integer by reference for the current count of Contact Objects within the array. This function will call inputContact member function for the array at index count. Increment count then return.
void displayContacts - this function will pass a const array of Contact Objects and a const integer by value for the current count of Contact Objects within the array. This function will traverse the array, calling each objects member function displayContact.
int searchContacts - this function will pass a const array of Contact Objects and a const integer by value for the current count of Contact Objects within the array. This function will create a temporary cstring of size 32, prompt the user for a first name value to search for and input into the temporary cstring. The function will then traverse array of Contacts searching for first name that matches the user\'s input. If a Contact\'s first name matches the inputed value, return the index at which the Contact was found. If there was no match, return -1.
void displayMenu - this function will print the menu with options to \'Add New Contact\', \'Display All Contacts\', \'Search Contacts\', and \'Exit\'
