    void    set(void);
    void    print(void);

As mentioned above, class definitions in TC may declare what methods are members of the class.  This declaration for the set() method is a little different from the one used in the beginning of this chapter*.  In C, all procedures are functions, which may RETURN a value upon completion.  If we wish to declare a function which does not return a value, we say it returns 'void'.  The declaration for the set() method also indicates that this function has no ARGUMENTS; i.e., a void argument.  It is good practice to explicitly state the types of values accepted by and returned by C functions, to allow the compiler to enforce type-checking.
