Question

C++: Create a simpe address book using arrays that allows a user to search, add, print, or delete an entry. The user should be allowed to search by first name, last name, phone number or address. The user should be asked to enter the file name. The array should hold 100 entries. The header file should contain two structs and one enum type.**** DO NOT USE LINKED LIST, NODES,OR VECTORS***

Bob, Smith, 123 456 7890 101 Market Street, Orlando, Fl, 12345 Susan, King, 234 568 1234 208 Main Drive, Nashville, TN, 45675 C++: Create a simpe address book using arrays that allows a user to search, add, print, or delete an entry.
