Quiz-1

The correct option is all of the above

Inline function is used only when our code is small.

When inline function is called, then the definition of called function is attached with the calling function.

It fast the execution speed, because our program run in sequence order. There is no jumps no branching.

So, definitely program's code size increases still, it fast the execution speed.

Protected data members are available only in the class hierarchy chain

Object in polymorphism exist in many forms so it doesn't check the type of object while it will definitely check the type of reference in the object.

Virtual keyword cannot be used with constructors as constructors are defined to initialized an object of particular class hence no other class needs constructor of other class.

Dynamic cast: Dynamic casts can be used to safely cast a superclass reference into a reference to a subclass in a class hierarchy.

Dynamic binding: Determining at run time what method to invoke.

Data hiding: Expose only necessary information to the client.

Dynamic loading is a mechanism by which a computer program can, at run time, load a library into memory, retrieve the addresses of functions and variables contained in the library, execute those functions or access those variables, and unload the library from memory

Two or more functions can have the same name but different parameters

Ad hoc polymorphism is a kind of polymorphism in which polymorphic functions can be applied to arguments of different types, because a polymorphic function can denote a number of distinct and potentially heterogeneous implementations depending on the type of argument to which it is applied.

C++ supports two types of polymorphism: Compile-time polymorphism, and Runtime polymorphism.

The statement is correct because, derived class has no knowledge of its parent. Because its top-down approach.
