Requirements and Specifications
Description
This goal of this project is to build an information manager similar to a rolodex (see http://en.wikipedia.org/wiki/Rolodex). A physical rolodex is made up of cards arranged in alphabetical order by [Last Name, First Name]. Each card contains some information, usually name, address, phone number and type of business (why the person is in the rolodex). The physical mechanism of using a rolodex is turning the group of cards and flipping through them. When the last card is read, the rolodex is then at the start of the list since a rolodex is built on a circular track.
Design Notes
For this project you'll implement a Card class (in Card.h and Card.cpp), a Rolodex class (in Rolodex.h and Rolodex.cpp), and a main() function (in main.cpp). The code in main() reads interactive commands that perform actions on its Rolodex object (like add a card, search for a card, list the rolodex cards, etc).
The Card class is used to represent a single Rolodex card. This class has std::string data members for First name, Last name, Occupation, Address (entire address can be in one string), and Phone number. It has get/set member functions to allow getting and setting of the member data values (e.g. first name), and a show(ostream& os) function that knows how to display the card on the supplied ostream parameter. This class does not know about Rolodex functionality, it just encapsulates a single card's information.
