Which feature of OOP allows the same function name to have different implementations?

• Abstraction

• Polymorphism

• Encapsulation

• Inheritance

Which C++ feature helps avoid code duplication?

• Inheritance

• Virtual functions

• Operator overloading

• Destructors

Which of these is used to free memory allocated with new?

• free()

• delete

• remove()

• clear()

Which of these concepts binds code and data together?

• Polymorphism

• Encapsulation

• Abstraction

• Overloading

The process of defining more than one function with the same name but different parameters is called:

• Function overriding

• Function overloading

• Operator overloading

• Inheritance

Which of the following supports runtime polymorphism?

• Virtual functions

• Function overloading

• Operator overloading

• Inline functions

Virtual functions are declared using:

• virtual keyword

• dynamic keyword

• override keyword

• polymorphic keyword

Which type of binding is used in virtual functions?

• Early binding

• Late binding

• Static binding

• Compile-time binding

Function overriding requires:

• Same name, different parameters

• Same name, same parameters, and inheritance

• Same name, different return type

• None

If a base class pointer points to a derived class object and the function is virtual:

• Base version is called

• Derived version is called

• Random

• Error
