CCSU BCA SEM 3 Object Oriented Programming UNIT 1 Introduction to C++ Basic terms and ideas|

Introduction to Object-Oriented Programming (OOP)

• Welcome to the channel 'Code Yourself Academy' as we begin the second year course on Object-Oriented Programming Language (C++) in the third semester.

What is Object-Oriented Programming?

• OOP focuses on using objects in programming, emphasizing a real-life analogy.

• It introduces concepts that enhance the programming experience beyond C, specifically in C++.

Why C++?

• C++ is seen as an advanced version of C, incorporating changes necessary for improved programming structure.

• Students familiar with C will find transitioning to C++ enjoyable. For those new, a quick review of C will be provided.

Course Outline

• Unit 1: Introduction to OOP

  • Basic terms and ideas related to OOP.

• Unit 2: Classes and Objects

  • Focus on classes and objects, crucial for understanding C++.

• Unit 3: Inheritance and Polymorphism

  • Key topics to discuss advanced features in C++.

• Unit 4: Generic Functions, File Handling, and Exception Handling

  • Practical applications of C++ in real programming scenarios.

OOP Approach Explained

• The OOP approach emphasizes binding together data and functions that operate on the data.

• Functions can only be accessed by authorized entities, promoting encapsulation and data protection.

Differences between C and C++

• In C, any function could be accessed or modified by any user, enhancing transparency but compromising security.

• C++ restricts access to functions, ensuring that only those with authorization can view or modify them.

Understanding Procedural vs Object-Oriented Languages

• Procedural Languages (e.g., C):

  • Focus on procedures or routines to execute programming tasks.

  • Programming follows a linear sequence based on an algorithm.

• Object-Oriented Approach:

  • Programming is framed around objects and their interactions, providing a more dynamic framework for coding.
