Due: Oct 30, 11:59pm?

Grading - auto-graded.  2 points per program.

See the files in HW/lab13/

You should run each one to see how it works.  Each prints out which
file from class you should use as a starting point.  As always,
create a ~/HW/lab13/ directory, and name your .cpp files the same
as the programs in HW/lab13/

More details and hints may be posted sometime.

lab13_io
  * for reading one line at a time, use getline (the C++ version)
  * use string find function to look for bad and well in first response,
    and look for Harry Potter, Hitchhiker's Guide, Lord of the Rings in second respons

lab13_files
  * either read one line at a time (and write it out to f_out), or read
    one character at a time (and write it out to f_out) using get

lab13_overloading
  * add operators to rational class for - / *
  * read in q1.top, q1.bottom, q2.top, q2.bottom with cin
  * compute each of the operations and print them
  * note - you do need to use the file as it was.

lab13_stack
  * just adding cout statements for push/pop, and doing an operation

lab13_vector
  * vector should be of double
  * loop should read double
  * after cin while loop, have a for loop to compute total
  * after total is calculated, loop through the numbers and print percentages

My output -

(Programmer's note: responses to try - 
 well, bad, Harry Potter, Hitchhiker's Guide, Lord of the Rings)
(And string comparisons in program are case sensitive.)

Hello.  How are you? 
  Awesome, me too.
What is your favorite movie? 
  Okay precious.
Alright, I have to go.  See you later.
