FREE Bachelor of Computer Engineering Object Oriented Programming Questions and Answers

Question 1

Who invented the OOP?

Accepted Answer

Alan Kay

Answer

Alan Kay is widely credited with coining the term 'Object-Oriented Programming' and developing the Smalltalk language, which was a pioneering object-oriented language. His work at Xerox PARC in the 1970s laid much of the conceptual groundwork for OOP as we know it today. While Simula introduced many OOP concepts earlier, Kay's contributions were pivotal in popularizing and defining the paradigm.

Question 2

What does a general definition of OOP not include as an attribute?

Accepted Answer

Duplicate/Redundant data

Answer

Object-Oriented Programming (OOP) aims to reduce data redundancy and improve data integrity through concepts like encapsulation and data hiding. Attributes like code reusability (via inheritance), efficient code, and modularity are core benefits and characteristics of OOP. Duplicate/redundant data is generally a problem that OOP seeks to mitigate, not an inherent attribute.

Question 3

Which programming language was the first to focus solely on objects?

Accepted Answer

SmallTalk

Answer

Smalltalk, developed by Alan Kay and his team in the 1970s, was the first programming language to fully embrace and implement the object-oriented paradigm, where everything is an object. While Simula introduced object-oriented concepts earlier, Smalltalk was designed from the ground up with a pure object model, making it a foundational language for OOP.

Question 4

When did the OOP concept initially come into existence?

Accepted Answer

1970’s

Answer

The core concepts of Object-Oriented Programming, including the term itself, were largely developed and popularized in the 1970s. Alan Kay's work on Smalltalk at Xerox PARC during this decade was instrumental in defining and demonstrating the paradigm. While Simula in the 1960s had some object-oriented features, the 1970s saw the formalization and significant advancement of OOP.

Question 5

What attribute of OOP denotes code reuse?

Accepted Answer

Inheritance

Answer

Inheritance is the OOP principle that directly enables code reuse. It allows a new class (derived class) to inherit properties and methods from an existing class (base class). This means that common functionalities can be defined once in a base class and then reused by multiple derived classes, reducing redundancy and promoting modularity.
