Using a cast operator to assign an array of base-class-type elements to an array of derived-class-type elements is an example of contravariance.

Question

Quizplus · Accepted Answer

This is because the cast operator converts the base-class-type elements to the derived-class-type elements, which means that an array of base-class-type elements can be assigned to an array of derived-class-type elements. Contravariance refers to the ability to assign a derived class type to a base class type, which is the opposite of this situation.
