/**
 * This program will get a line of input from the user.  It will

 * line will contain 25 copies of the character.
 *
 * This simple program is meant to demonstrate the use of subroutines,
 * and especially the case where one routine calls a subroutine
 * which then calls another subroutine.  It is not a useful program.
 * 
 * (Note:  It doesn't matter in what order the subroutines are
 * listed in the class.  A subroutine can always be used anywhere
 * in the class that defines it, even if the definition occurs
 * physically after the point where it is called.)
