Which operator cannot be overloaded in C++?

  1. ::

  2. ++

  3. +

  4. ->

The correct answer is: ::

The : operator is the scope resolution operator in C++, and it is not possible to overload it because it has a specific predefined meaning. The ++ operator is an increment operator, which can be overloaded. The + operator is an addition operator, which can also be overloaded. The -> operator is a member access operator, which can also be overloaded. Therefore, the only operator that cannot be overloaded in C++ is the scope resolution operator (::).
