consider the operator ++ for the INT class just discussed.the reqirement is to have the operators ,
++a
&
a++

++a will be resolved as a.operator ++()
a++ will be resolved as a. operator ++(0)

In order to avoid this confusion , all postfix unary operators take in a dummy integer .

Thus,
++a will be resolved as a.operator ++()
a++ will be resolved as a. operator ++(0)
