I always call it the "arrow operator", but I'm sure it has an official name. I quickly skimmed the C++ standard and didn't see it mentioned by name.

The -> is called the arrow operator. It is formed by using the minus sign followed by a greater than sign. Simply saying: To access members of a structure, use the dot operator. To access members of a structure through a pointer, use the arrow operator.
The object operator, -> , is used in object scope to access methods and properties of an object. It's meaning is to say that what is on the right of the operator is a member of the object instantiated into the variable on the left side of the operator.
Difference between Dot and Arrow Operators in C. Question: What is Difference in Accessing Structure Members Using Dot '. ' and Arrow Operator '->' in C Language? No difference in the result!
The C++ standard just calls it "arrow" (§5.2.5).
