Question

c++)Which situation would require the operator to be overloaded as a non-member function? provide an example of your answer choice of when this would occur.

a. The overloaded operator is =.

b. The left operand is an int.

c. The operator returns a reference.

d. The left operand must not be a class object (or a reference to a class object).

Answer 1

The left operand is an int.

if left operand is of class type, then we use member function for assignment operator.
but, if we use int as left operand, then we must use a non-member function for assignment operator.
