Question: 1 / 565

What concept does the example of object slicing demonstrate?

Polymorphism

The concept of object slicing is the result of data being lost when assigning a derived class object to a base class object. This limitation arises due to the compiler not recognizing the full capabilities of the derived class, and therefore only copying the base-class portion of the object into the new variable. This example specifically demonstrates polymorphism, as the derived class object is temporarily treated as a base class object, leading to data loss. Encapsulation refers to the bundling of data and methods within an object, while inheritance is the process of deriving new classes from existing ones. Memory management, on the other hand, is the act of managing computer memory usage in a program. Therefore, the correct concept demonstrated in this example is polymorphism.
