C++/OOPS Interview Questions With Answers - Part V.

Here, are some sample questions based on "C++/OOPS Programming language". Read it carefully as these questions will help you in cracking any interview.


Question - 21) What is polymorphism? Explain with an example ?

Answers: Polymorphism is the property by which the same message can be sent to different objects of several different classes, and each object can respond to it in a different way depending upon its class. In C++, polymorphism is implemented through overloading.

A function name having several definitions that are differentiable by the number of types of their arguments is known as function overloading. For example,

float area (float a)
{
return a * a;
}
float area (float a, float b)
{
return a * b;
}


Question - 22) What is public, protected and private ?

Answers: Public, protected and private are access labels in a class. A class provides three access labels namely private, protected and public.

A member declared as public is made available to the outside world. That is, it can be accessed by any function, any expression in the program but only by using an object of the same class type.

A member declared as private or protected remains hidden from outside world and it can only be accessed by the member functions and friend functions of a class.


Question - 23) What is the significance of the protected access specifier ?

Answers: The members having protected accessibility are hidden from outside world, like private members, but when inherited, they remain visible in the derived class unlike private members.


Question -24) Do 'derivation' and 'friendship' mean the same ?

Answers: No. ‘Friendship’ gets the access privilege for private and protected members of a class. However, ‘derivation’ from that class gets access privilege only for protected members of the class.


Question - 25) Enlist some advantages of object oriented programming ?

  • Re-usability of code.
