Explanation / Answer

Question 1.1.

Object-oriented programming generally focuses on

Answer: Only A, B, and D

Question 2.2.

Public data members are the components of a class definition that can be overloaded.

Answer: Public data members

Question 3.3.

Method overloading is a feature in Object-oriented programming that allows a class to have two or more methods with the same name. They only differ in the data type of arguments passed or the number of arguments passed.

public int Walk(int x, int y) ; public void Walk(int x, int y, int z) In this option, the number of arguments passed are different.

public void Dance() ; public int Dance(int x): In this option, the number of arguments passed are different.

Answer: Only B and C

Question 4.4.

It is possible to create sub-classes and sub-objects in Object-oriented programming.

In object-oriented programming, we design the program as a set of cooperating methods.

Answer: Only A and C

Question 5.5.

The most appropriate choice for a method in a Cube class will be to calculate volume.

Answer: CalculateVolume() or Volume()

Question 6.6.

A method that is declared as private in a class cannot be called through an object of that class.

Access specifiers can be used by the programmer to control the scope of a data member of a class.

When designing a class, it is important to know the purpose of the class and who will use the class.

Answer: All of the above
