Functions vs Methods

Difference between Functions and Methods

S.No	Functions	Methods
1	Functions do not have any reference variables	Methods are called by reference variables
2	All data that is passed to a function is explicitly passed	It is implicitly passed the object for which it was called
3	It does not have access controlling i.e.,Function(other than static functions) declares and defines anywhere in the code	It has access controlling i.e.,Method should declare and define in the class only
4	Function applies to both object oriented and non-object oriented language(procedural language.eg. C, Scripting language eg; JavaScript etc)	Method is only applicable to object oriented programming language like C++, C#, Java etc

Summary:

A function is just a part of code that executes code and can return something.

A method is, in OOP, a function that is bound to a class. As in C# there are no stand-alone functions, every function in C# is a method
