/*
 * T01n06.java -- Based on the given letter grade, this program will display
 * an encouraging message to the user.  This demonstrates how to indent
 * a deeply-nested set of IF statements.  Doing it the normal way makes the
 * text too wide to be conveniently viewed or printed.
 *
 * This is the first program we've seen that uses chars.  You can read
 * chars, write them, and compare them.  If you want to use a char as a
 * constant literal, put the symbol in single quotes, like this:  'K'
 * Don't use the left quote (`) for this, though.
 *
 * Questions:  Would this program accept 'b' as a legal letter grade?
 *             Should it?  If so, how would you change the program to
 *             accept the lower-case versions of the legal letter grades?
 *
 * Note:  To get a single character from the keyboard, the Scanner class
 * forces us to read the entire line and pick out the character.  This
 * means reading a String, and we haven't quite got to the String class
 * yet.  So, just accept this for now, and we'll explain it later.
