Program: C Strings 
Version: 1.1
Created/Revised: 
File: cstrings.cpp
Programmer: C. S. Tritt, Ph.D.
Course: CS-150
Assignment: C Strings Example
Compiler: Microsoft Visual C++ 6.0
Target: Win32

Description:

  This program demonstrates the use of C strings in
  C++. The problem solved involves asking the user
  for a size code (L+, L, M, S and S-) and displying the
  corresponding text (Extra large, Large, Medium, Small
  and Extra small, respectively. This version also recognizes
  lower case letters.

  This program uses a somewhat odd approach for demonstration
  purposes. It does not do error checking and it is possible
  to overflow the input string with improper input.

Revisions:

  There have been no major revisions of this program.

Constants and Variables:

  See code for constant and variable descriptions.
