order of calling overloaded operators

[ES Kim]

iterator classes provide overloaded operators like this in general:

template <typename T>
class Iterator
{
Iterator operator++(int); // postfix ++
T& operator*();
};

Iterator<int> i;
*i++;

You know postfix ++ has higher precedence than unary *.
Does it gaurantee that postfix ++ is called before unary * operator?

It`s the dereferencing operator, not unary * (which does not exist).

Of course. The point of operator precedence is to guarantee the order
in which these operators are called.

*p++ is always *(p++) and a+b*c is always a+(b*c).

Oh, come now. It's a unary operator represented by the symbol '*', and
you and everybody else knew exactly what the OP meant. In fact,
§5.3.1 [expr.unary.op] uses the exact term "the unary * operator" to
refer to this entity. Perhaps you just enjoy bullying, rather than
helping to inform? If you're going to be pedantic, have the decency to
be correct.

It was my intention to remove that line, but I forgot before posting. I
apologize.

True.
