C++ need help programming something like this? 

This project will help you show your mastery of arrays, C-strings, classes, and libraries. Write a program to handle a user’s rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu – don’t force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don’t forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When they choose the print option, make a nicely formatted table of their current entries (if any). (See the class roster lab for an example of a fine table format – and possible gotcha’s.) When they choose to find an entry, go to a submenu: 1) find by Name 2) find by Address 3) find by Phone number 4) find by Email address 5) Return to Main Menu All of these searches are to be case-insensitive content searches. (In other words, if the rolodex contains a person named Vishal Herrera, they should be found by searches by name of: sh SH al h al H herrera HERRERA, etc. as well as of Vishal Herrera.) Question: Should you print all matches to a search or just the first one? All menus are to be choosable by both number and capitalized letter(s).
