The operators # and ## are
used only by the preprocessor.
Depending on context, the same operator can have more than one meaning. For
example, the ampersand ('&'
) can be interpreted as
A & B
);
&A
);
'&'
is a unary operator; in the second, the '&'
is a
binary operator. Similarly, the comma ','
may act as an operator and as a
punctuator, etc.
