lvalue

[Arvind]

Hi All,

I have a question.

int i=9;
int *p = &(++i); // correct , doesn't give error.
//whereas
int *p = &(i++); // this gives an lvalue error.

WHY ????

[Venkatesh Raja]

What compiler did u use to compile this ?
In my gcc compiler, both the statements gives error.

It may be compiler specific.

This may be tha alternative soln.
Assign the variable i to p (ie . p = &i) and do pointer arithmetic on p.

hi,
when you overload suffix operator u return this pointer that is
object pointer itself so first statement works
while
when you overload prefix operator you return by value that is u store
object current state in temporary variable then increment objects
value and return temp object value hence temp obj address cannot be
assigned to *p
i think this is the reason
