Refactor Assignment 2 into 3 project related files. Customer.h - Class Specification Customer.cpp - Class Implementation (Methods) TestCustomer.cpp - Your code that performs the logic from Assignment 2. The 3 files need to be named as listed above and should compile without errors. Deliverables are the 3 files listed above.  Assingment 2: #include #include #include using namespace std; //My main method int main() {     Customer cust;     cust.setCustomerNumber(1);     char name[NAME_SIZE];     char streetAddress_1[STREET_SIZE];     char streetAddress_2[STREET_SIZE];     char city[CITY_SIZE];     char state[STATE_CODE_SIZE];     int zipCode;     do {         cout << "Input name: ";         cin.getline(name, NAME_SIZE);     } while (!cust.setName(name));     do {         cout << "Input street address 1: ";         cin.getline(streetAddress_1, STREET_SIZE);     } while (!cust.setStreetAddress1(streetAddress_1));     do {         cout << "Input street address 2: ";         cin.getline(streetAddress_2, STREET_SIZE);     } while (!cust.setStreetAddress2(streetAddress_2));     do {         cout << "Input city: ";         cin.getline(city, CITY_SIZE);     } while (!cust.setCity(city));     do {         cout << "Input state code: ";         cin.getline(state, STATE_CODE_SIZE);     } while (!cust.setState(state));     do {         cout << "Input zip: ";         cin >> zipCode;     } while (!cust.setZipCode(zipCode));     // displaying all customer details     cout << endl << "Details of Customer: " << endl;     cout << "Customer Number: " << cust.getCustomerNumber() << endl;     cout << "Name: " << cust.getName() << endl;     cout << "Street Address 1: " << cust.getStreetAddress1() << endl;     cout << "Street Address 2: " << cust.getStreetAddress2() << endl;     cout << "City: " << cust.getCity() << endl;     cout << "State: " << cust.getState() << endl;     cout << "Zip code: " << cust.getZipCode() << endl;     return 0; } //Declaring My Function NAME_SIZE/STREER_SIZE/CITY_SIZE/STATE_CODE_SIZE const int NAME_SIZE = 20; const int STREET_SIZE = 30; const int CITY_SIZE = 20; const int STATE_CODE_SIZE = 3; //Customer Details   class Customer { private:     long customerNumber;     char name[NAME_SIZE];     char streetAddress_1[STREET_SIZE];     char streetAddress_2[STREET_SIZE];     char city[CITY_SIZE];     char state[STATE_CODE_SIZE];     int zipCode; //Public Class as Assingment required  public:     void setCustomerNumber(long cn);     bool setName(char n[]);     bool setStreetAddress1(char sa[]);     bool setStreetAddress2(char sa[]);     bool setCity(char c[]);     bool setState(char s[]);     bool setZipCode(int z);     long getCustomerNumber();     char* getName();     char* getStreetAddress1();     char* getStreetAddress2();     char* getCity();     char* getState();     int getZipCode(); }; // setters void Customer::setCustomerNumber(long cn) {     customerNumber = cn; } bool Customer::setName(char n[]) {     //Confirmed NAME is not an empty string      //using Strcpy to copy one string to another     if (strlen(n) > 0)     {         strcpy(name, n);         return true;     }     return false; } bool Customer::setStreetAddress1(char sa[]) {     // Confirmed StreetAddress1 is not an empty string     if (strlen(sa) > 0)     {         strcpy(streetAddress_1, sa);         return true;     }     return false; } bool Customer::setStreetAddress2(char sa[]) {     // Confirmed StreetAddress2 is not an empty string     if (strlen(sa) > 0)     {         strcpy(streetAddress_2, sa);         return true;     }     return false; } bool Customer::setCity(char c[]) {     // Confirmed city is not an empty string     if (strlen(c) > 0)     {         strcpy(city, c);         //all characters of city are letters         for (int i = 0; i < strlen(city); i++)         {             city[i] = toupper(city[i]);             if (city[i] < 'A' || city[i] > 'Z')                 return false;         }         return true;     }     return false; } bool Customer::setState(char s[]) {     // Confirmed state is not an empty string     if (strlen(s) > 0)     {         strcpy(state, s);         // Confirmed all characters of state are letters         for (int i = 0; i < strlen(state); i++)         {             state[i] = toupper(state[i]);             if (state[i] < 'A' || state[i] > 'Z')                 return false;         }         return true;     }     return false; } bool Customer::setZipCode(int z) {     // Confirmed zipCode is between [0,99999]     if (z >= 0 && z <= 99999)     {         zipCode = z;         return true;     }     return false; } //Printing all the outputs  long Customer::getCustomerNumber() {     return customerNumber; } char* Customer::getName() {     return name; } char* Customer::getStreetAddress1() {     return streetAddress_1; } char* Customer::getStreetAddress2() {     return streetAddress_2; } char* Customer::getCity() {     return city; } char* Customer::getState() {     return state; } int Customer::getZipCode() {     return zipCode;
