What is the difference between a method and a function?

A function is a piece of code that is called by name. It can pass in some data (parameters) for processing, then return some data (return value), or no return value.

All the data passed to the function is passed explicitly.

The method is also a piece of code and is called by name, but it is associated with an object. Methods and functions are roughly the same, but there are two main differences:

1. The data in the method is implicitly passed;
2. Method can manipulate data inside a class (remember that an object is an instantiation of a class – A class defines a data type, and an object is an instantiation of that data type)

The above is just a brief explanation, ignoring the scope of the problem.
