Question

PLEASE DO IN C++

Create an object-oriented program that initially allows the user to save customer information in the list and to search for a customer by specifying the customer’s ID.

Sample Run

Customer Information Management System

---------------------------------------------------------------

CUSTOMER DATA ENTRY:

Full Name (First, Last): Jenny Ha
Company: Convergent Laser Technologies
Street: 1000 International Ave
City: Oakland
State: CA
Zip Code: 94506
ID: 100

Continue Your Data Entry? (y/n): y

Full Name (First, Last): Bill Martinez
Company: Cisco Systems
Street: 2000 Jackson St
City: San Jose
State: CA
Zip Code: 95112
ID: 100
This ID exists! Try again.
ID: 200

Continue Your Data Entry? (y/n): n

---------------------------------------------------------------

CUSTOMER DATA SEARCH:

Enter Customer ID: 100

Jenny Ha
Convergent Laser Technologies
1000 International Ave
Oakland, CA 94506

Continue Your Data Search? (y/n): y

Enter Customer ID: 200

Bill Martinez
Cisco Systems
2000 Jackson St
San Jose, CA 95112

Specifications

• Draw a UML class diagram (a hand drawn image is also accepted) for your project.
• Create a Customer class to store the customer data.
• This class should include private data members: full name, company, street, city, state, zip code, and id.
• This class should include public member functions: a constructor, getters, and setters. In addition, it should include a public member function that returns the full address (street, city, zip code, and state).
• When the program starts, it should ask the user to enter the customer data and save it in an array of Customer objects. For this project, you can initially define the array with twenty elements and make sure each customer has a unique id.
• Note that the size of the array is fixed, so your program should check the maximum number of customers in the array to prevent the out of bound access error.
• To find the customer with the specified ID, you can loop through each Customer object in the array of Customer objects and check whether the specified ID matches or not.
• If the specified ID isn’t found, display an appropriate message.
