Accepted answer
Basically 'method' and 'function' are same.Method is the correct term for a function associated with a class .but developer change their convenient method and function as in c# works that where as we mention "void" that is a method . function is a without void and return something .
Method:
public void mypgm()
{
//code
}
Function:
public string mypgm()
{
//code
return string
}

Functions are defined outside of classes, while Methods are defined inside and they are probably part of classes.

- Function → Free (Free means it can be anywhere, no need to be in an object or class)
- Method → Member (A member of an object or class)
Method & Function are not the same

Hi
Function is that piece of code that has name ( called function name) and data to operate on ( called arguments) that is provided in the parenthesis adjacent to the function name. All function arguments are explicit.

Method on the other had can be viewed as a function that acts on an Object. This object is an instance of a class (blueprint of that instance). Method will always have an implicit argument as a reference to self. For example in python you use self , or in Java you use this.

So to sum it up simplistically speaking "method" is object oriented word for function .

Hi,

Functions :

Functions have independent existence means they can be defined outside of the class. Ex:- main() function in C, C++ Language
Functions are defined in structured languages like Pascal,C and object based language like javaScript
Functions are called independently.
Functions are self describing unit of code.
Methods :

Methods do not have independent existence they are always defined with in class. Ex:- main() method in C# Language that is defined with in a class
Methods are defined in object oriented languages like C#, Java
Methods are called using instance or object.
Methods are used to manipuate instance variable of a class.
