/*  The corresponding Java and C++ programs demonstrate 'bad' ways
    of writing switch-case constructs. C# is a better language
    in the sense that it does not accept switch-case constructs 
    that do not contain break statements. For this reason,
    this is quite an unnecessary program as a C# program.
    However, I whote this program so that it behaves almost like the
    corresponding program in the Java book.

    This program is not presented in the C# book.

    This program would be a too difficult program for Chapter 6
    because classes string and ArrayList are in use.
