What is a method, property and function?

Question

Yes, I'm struggling with that. I cannot tell them apart because every explanation I read is so obscure and philosophical enough. Can someone clarify these definitions for me? Thanks guys.

Are these definitions as applicable to procedural programming as oop? Thank.

Answer 1

A function is a combination of commands related to each other to achieve a specific result. It can take arguments and return a result. If a function does not return a result, it is usually called a procedure. Examples:

function drawLine(x1, y1, x2, y2):
  // draws a line using Bresenham algorithm from x1,y1 to x2,y2.
  // doesn't return anything

function <number> add(a, b):
  // adds a to b and returns the result as a number
  return a + b
