Difference between Procedure Oriented and OOP

Difference between Procedure Oriented and OOP

• Definition:
  • Procedure-Oriented Programming (POP):
    • Focuses on writing procedures or functions to perform tasks.
  • Object-Oriented Programming (OOP):
    • Focuses on creating objects that contain both data and methods.
• Data and Functionality:
  • POP:
    • Data and functions are separate and independent entities.
  • OOP:
    • Data and functionality are encapsulated together within objects.
• Encapsulation:
  • POP:
    • Does not emphasize encapsulation.
    • Data can be accessed and modified directly by any part of the program.
  • OOP:
    • Emphasizes encapsulation, bundling data and methods together within objects.
    • Access to data is controlled through methods, promoting data integrity and hiding implementation details.
• Abstraction:
  • POP:
    • Limited support for abstraction.
    • Functions may abstract certain operations, but data structures and algorithms are often exposed.
  • OOP:
    • Strong support for abstraction.
    • Classes define abstract data types, allowing complex systems to be modeled at higher levels of abstraction.
• Inheritance:
  • POP:
    • Does not support inheritance.
    • Code reuse is typically achieved through function libraries or by copying and pasting code.
  • OOP:
    • Supports inheritance, allowing classes to inherit properties and behavior from parent classes.
• Polymorphism:
  • POP:
    • Polymorphism is limited or non-existent.
  • OOP:
    • Supports polymorphism, allowing objects of different classes to be treated uniformly through a common interface.
• Examples:
  • POP:
    • C programming language is often used as a procedural programming example.
  • OOP:
    • Languages like Java, C++, Python, and Ruby are commonly used for OOP.
