Due: 11:59 P.M. Wednesday, October 4, 2006

NOTE:  Please follow your lab instructor's directions for submitting your
assignment to your ENGR 112 section on http://csnet.cs.tamu.edu.

NOTE:  Homework will be graded by how it runs on unix.cs.tamu.edu.  You may
develop and test your homework on any platform, but make sure it runs
correctly on unix.cs.tamu.edu. 

NOTE:  Begin each file according to the following sample--
// hw5pr1.cpp (assignment number and problem number)
// <Your Name>
// ENGR 112-5xx (your section number)
// Due 11:59 P.M. Wednesday, October 4, 2006
// In support of the Aggie Honor Code, I have neither given nor received any
// unauthorized help on this assignment.

1. (10 points) Exercise 1 in section 6.12.  Name your program hw5pr1.cpp.  Hint:
Add one more rule to the grammar and implement it.

2. (10 points) Read exercise 10 in section 6.12 and then do the following
simplified version: Use the letters p, n, d, and q for the coins, so that input
looks like
	3p + 4n + 5d + 2q
Now modify your calculator program from the previous homework by adding rules 
like
	case 'q':
		return left * 25;
so that the output is the value in cents (118 in this example).  Name your 
progam hw5pr2.cpp.  Hint: Be sure your exit command is 'x', not 'q'.

3. (10 points) Choose some table of data of your choice (say CD's or movies)
with at least 5 rows and 2 columns, e.g.,
	Caedmon's Call		Guild 2
	Newsboys		devotion
	Kingpin Wrecking Crew	Abolition Strategy
	Krystal Meyers		Krystal Meyers
	MercyMe			Coming Up To Breathe
Define a struct (or class) named Row and create a vector of Rows with your 
data.  Then ask the user for an item number (starting at 1, not 0) and display 
that row; repeat until the user enters 0.  Thus item 5 is the MercyMe CD.
Name your program hw5pr3.cpp.
