Contact Lists

Create a menu-driven program to emulate a Contact Lists Application. You might see such apps in smartphones, you are free to go ahead and take ideas from your own contact applications.

Your menu-driven program must look like:

Welcome to DBC's Contact List App
Press 1 to add a new contact
Press 2 to view all contacts
Press 3 to search for a contact
Press 4 to delete a contact
Press 5 to exit program 

The 'Add a new contact menu'

    // a field to store the last name
    // a list to store multiple contact numbers (i.e a list of numbers)
