.OBJECT ORIENTED CONCEPTS USING C++

.OBJECT ORIENTED CONCEPTS USING C++

Short answers

1. Expand OOP's language

• Object Oriented Programming Language.

2.What sort of software is used to solve any specific problem?

• The application software is used to solve any specific problem.

3. What is an object? Or What is the significance of an object?

• An object is a group of related functions (operations) and data that serves those functions.
• An object is a kind of a self-sufficient “subprogram” with a specific functional area

4. What is polymorphism?

• The ability of an object to respond different messages is called polymorphism.
• Polymorphism reduces software complexity,
• 5. What is inheritance?

• The process of acquiring Base class properties is called inheritance.
• Inheritance increases the functionality of a derived class and also promotes reusability of code

5.What is an Encapsulation ?

• The mechanism by which the data and functions are bound together within an object definition is called as Encapsulation

6. How is Polymorphism different from inheritance ?

Polymorphism

• The ability of an object to respond different messages is called polymorphism.
• Polymorphism reduces software complexity,

Inheritance

• The process of acquiring Base class properties is called inheritance.
• Inheritance increases the functionality of a derived class and also promotes reusability of code

7.What does state and behavior of an object refers?

• State refers to the physical features of the object,
• Behaviour refers to the the kind of functions of the object.

8.How will we treat the calculator as object is Object Oriented programming language.

• In Object Oriented Programming language calculator is treated as follows

Object – calculator

Data :

Number1,result, operator, Number_backup

Functions :

Additon()

Subtraction()

Erase_Memory()

Display_Result()

9.How Object Oriented Programming solve a problem given?

• Object Oriented Programming facilitates the way of problem solving by combining 'data' and 'operations' that are to be performed on the data.

10.Define class.

• Classes are user-defined data types
• It is a template for entities that have common behaviour.
• It allows programs to organize as objects that contain both data and functions

11.Define derived class.

• The derived classes are power packed
• They include to functionality of the base class along with its own unique features

12. Define Data hiding or Abstraction of data provides?

• Data hiding or Abstraction of data provides security to data,

The functions defined outside the class cannot access its data

13.List any two advantage of Object Oriented Programming.

• Inheritance increases the functionality of a derived class and also promotes reusability of code.
• Data hiding or Abstraction of data provides security to data
• Polymorphism reduces software complexity,
