i.e.,Function(other than static should declare and define in the class
functions) declares and defines only
anywhere in the code
4 Function applies to both object Method is only applicable to object
oriented and non-object oriented oriented programming language like
language(procedural language.eg. C++, C#, Java etc
C, Scripting language eg;
JavaScript 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
