++ and -- operators

I have a question about the ++ and -- operators; in C++, these
add/subtract 1 from a variable, and store that new value in the
variable.  However, in the examples on pg. 2 of the assignment,
the example for ++ says "++(a + b * c)".  Obviously, this example
shows ++ working on an expression rather than a single variable,
and so storing a new value would be impossible.  So, should we
implement ++ and -- so that they just add/subtract 1 from any
expression, or should we have them add/subtract 1 from a variable
and store the result as the new value of the variable?

Thanks.
