Which of the following operators can not be overloaded in C+ + ?

  • A.*
  • B.+ =
  • C.= =
  • D.: :

Answer: D

The scope resolution operator :: cannot be overloaded in C++. Along with the member access operator (.), the pointer-to-member operator (.*) and the conditional operator (?:), it is one of the few operators whose behaviour is fixed by the language.

The multiplication operator *, the compound assignment += and the equality operator == can all be overloaded as member or friend functions, which is why they are not the answer.
