Question

______ is a mechanism to achieve run time polymorphism. 

Options

• Operator Overloading

• Virtual Function

• Function Overloading

• Constructor

Answer 1

Virtual Function is a mechanism to achieve run time polymorphism. 

Explanation:

Runtime polymorphism can be achieved in object-oriented programming (OOP) through the use of virtual functions. A vtable (virtual table) is used at runtime to resolve the function call when a base class designates a function as virtual, allowing derived classes to override the function.
