If o is an object of a class emp and we want that both the statements o++ and ++o should get properly executed then we must overload both postfix and prefix operators. Following code shows how to overload them.
emp operator++( )
{
// pre incrementation
return *this ;
}
emp operator++ ( int )
{
// post incrementation
return *this ;
}
In the postfix function we must write int in parentheses. It is not a parameter of the function it is only a signal to the compiler to create a postfix version of the operator.
