Doe s operator -have a name? Like bool operator <(..) is named the
less-than operator.

I call it the "operator for member selection via pointer", or perhaps just
"the arrow operator".

Thanks; Does C++ standard have this name? Do you know?

The standard document refers to it literally as "the -operator", or
sometimes as "arrow".

The "class member access" operator.

Sort of. What it says is ($5.2.5):

A postfix expression followed by a dot . or an arrow ->,
optionally followed by the keyword template (14.8.1), and
then followed by an id-expression, is a postfix
expression.

I guess based on that you could call it the "arrow operator", but the
standard almost goes out of its way to avoid that term (or any other).

I tend to "read" it as "pointing at", since I learned it from C back in
1984, and it was used with pointers.

But I don't believe the Standard has any "official" name, short of what
Jerry post it.

The caption of 5.2.5 is "Class member access". I've seen the term "member
access for pointer" used when referring to the "arrow" operator, '->'. At
the same time, the paragraph 2 of the same subclause uses the term "arrow"
(in parentheses) when talking about the "second option", i.e. the '->'.
So, both names are pretty official.

Also, 13.5.6 (which is about overloading of 'operator->') is titled as
"Class member access".

That's true of the C standard as well, it just uses -whenever it
wants to refer to the operator. I didn't see any other name used,
although I didn't make an exhaustive search.

I guess it's not too surprising, had C called it something C++ would
probably have used the same nomenclature.
