As in C, each of the arithmetic operators
^ can be used as a self operator.
The prefix operators
++ (increment by one) and
by one) are also defined.
int i=1; i += 2; int j=++i;
is equivalent to the code
int i=1; i=i+2; int j=i=i+1;
However, postfix operators like
i-- are not defined
(because of the inherent ambiguities that would arise with the
path-joining operator). In the rare instances where
i-- are really needed, one can substitute the expressions
