Please help!!
Develop a C++ application. The application defines and uses two classes: Customer and Contact. The Customer class has a vector of Contact as a one of the data members.
Requirements:
1. The class Customer should be implemented based on the class diagram shown below:
Customer
-CompanyName: String
-Address: String
-City: String
-State: String
-Zip: String
-Contacts: vector <Contact>
«constructor»+ Customer()
«constructor»+ Customer(companyname:String, address:String, city:String state:String, zip: String)
+setCompanyName(company_name: String)
+getCompanyName(): String
+setAddress(address: String)
+setCity(city: String)
+setState(state: String)
+setZip(zip: String)
+getAddress(): String
+getCity(): String
+getState(): String
+getZip(): String
+getFullAddress(): String
+addContact(contact: Contact)
+RemoveContact(contact: Contact): bool
+listContacts(): String
2. The class Contact should be implemented based on the class diagram shown below:
Contact;
-FirstName: String
-LastName: String
-Phone: String
«constructor»+ Contact()
«constructor»+ Contact(firstname:String, lastname: String, phone: String)
+setFirstName(firstname: String)
+setLastName(lastname: String)
+getFirstName(): String
+getLastName(): String
+setPhone(phone: String)
+getPhone(): String
+getContactInfo(): String
3. Description of the member functions for class Customer
*Customer() This constructor initializes CompanyName, Address, City, Zip to a zero-length string ("").
*Customer(address: String, city: String, state: String, zip: String) This constructor initializes CompanyName, Address, City, State and Zip using the arguments passed in.
*setCompanyName(), setAddres(address:String), setCit(city:String), setZip(zip:String) These setter functions update corresponding data members.
*getCompanyName(), getAddress(), getCity(), getZip() These getter functions returns corresponding data members.
*getFullAddress() returns the combined address with this format: <address>,<City>,<State>,<Zip>
*addContact(contact: Contact) Add a contact to the vector of Contact
*removeContact(contact: Contact) Compare the argument with the contacts in the vector of Contact, if the first name, last name and phone number match, remove the contact from the vector
*listContacts() Return a String that contains information of all contacts. The information of each contact is obtained by calling the getContactInfo of the Contact class.
Note: The word "return" in the description above means the "return" keyword in C++, rather than display on screen.
4. Description of the member functions for class Contact
*Contact() This default constructor initializes FirstName, LastName and Phone to zero-length string ("").
*Contact(firstname:String, lastname: String, phone: String) This constructor initializes FirstName, LastName and Phone using the arguments passed in.
*setFirstName(firstname: String) setLastName(lastname: String) setPhone(phone: String) These setter functions update corresponding data members.
*getFirstName(): String getLastName(): String getPhone(): String These getter functions returns corresponding data members.
*getContactInfo(): String returns a String with this format: <First Name> <Last Name> < Phone>
Note: The word "return" in the description above means the "return" keyword in C++, rather than display on screen.
5. Write a driver program as the client of the Customer class. It should instantiate an object of the Cusotmer class; then it should demonstrate the use of all member functions. However, only one constructor should be used.
