Arithmetic operators
Example
w Shorthand operations are usually very efficient and they can be combined with another expression.
X = A * B++; is equivalent to  X = A * B;
w  B = B+1;
w
X = A * ++B; is equivalent to  B=B+1;
w  X=A*B;
w
X = --C * (A + B); is equavalent to    C = C – 1;
w         X = C * (A + B);
w
X = C-- * (A + B); is equavalent to     X = C * (A + B);  C = C – 1;
Versions where the operator occurs before the variable name change the value of the variable before evaluating the expression.
