subscript operator in C++

Question

is subscript operator [ ] unary or binary operator ?

I'm quite new to C++ and was going through operator operloading and wondered is subscript a unary or binary?

Answer 1

The subscript operator is a binary operator in the strict sense as it takes two arguments, the reference to the object and the value.

int arr[3];

Here you can see that [] operator makes use of both arr and 3.
