Study Notes

Procedural Programming

  • Procedural programming involves writing programs made up of functions that perform specific tasks
  • Procedures operate on data items that are separate from the procedures themselves
  • Data items are commonly passed from one procedure to another
  • The focus of procedural programming is to create procedures that operate on the program's data

Object-Oriented Programming

  • Object-oriented programming is focused on creating objects
  • An object is an entity that contains data (known as data attributes) and procedures (known as methods)
  • Methods perform operations on the data attributes
  • Encapsulation is a key concept in object-oriented programming, where data and code are combined into a single object
