   This program demonstrates the concept of "scope."  In this
    example, the scope of the variable 'num' inside the inner
    braces lasts for only two statements.  Because 'num' is
    defined inside a separate set of braces, it is shielded
    from the outer value of 'num' and does not cause a redefinition
    error, but its value is lost upon exiting the inner braces.
    The variable 'num' inside the inner braces is actually a
    DIFFERENT variable than the 'num' defined outside the braces.
    However, had an 'int' statement not been used inside the inner
    braces, a new 'num' would not have been created and the value
    of the outer 'num' would have been changed.
