/*	Project 2 for CS 1704, Spring 2004
	
	Programmer:		John Christopher Humphreys
	OS:				Windows XP Professional
	System:			Pentium M, 512 MB
	Compiler:		Microsoft Visual Studio.net 2003
	Last Modified:	February 14, 2004

	Purpose-
	This program will store student data and data of certain items in two arrays.  Classes will be
	created to hold and manage data of each kind, and a class will manage the arrays.  Data can be 
	edited, printed, or cleared by the controlling class, and all commands, taken from an input file,
	will be processed and executed.

	Format for Comment Block provided by (http://courses.cs.vt.edu/~cs1704/spring2004/Standards/ProgramHeader.txt)

//	This program uses three classes, three input streams, one output stream, and four assert statements

	ofstream outdata ("output.data");			// Outputs all required data
	
	Control Database;					// Create object that will control all arrays

	assert (commanddata);			// Make sure "commands.dat" exists and works properly, if not, end program
	assert (outdata);				// Make sure outdata command was created properly
	string command;			// Next command taken from Input File
	commanddata >> command;			// Input next command
	
	while(command != "quit")		// Loop while quit command is not given

/*On my honor:

- I have not discussed the C++ language code in my program with anyone other than my instructor or the teaching assistants assigned to this course.

- I have not used C++ language code obtained from another student, or any other unauthorized source, either modified or unmodified. 

- If any C++ language code or documentation used in my program was obtained from another source, such as a textbook or course notes, that has been clearly noted with a proper citation in the comments of my program.

- I have not designed this program in such a way as to defeat or interfere with the normal operation of the Curator System.
