is there any big difference between API, library, framework?

Question

i came across them a lot but is there really a difference.

Answer 1

Think of a framework as an abstraction which only works when incorporated into your application, more like a skeleton whose flesh is your code. A library is a group of types which perform a particular task and you use it as a tool which you call when you need to accomplish a particular task. The API is the interface between you and the library and/or the framework (i.e. the exposed/visible methods) and it is what ties your code, the library and the framework together.

Hope this makes it a little more clearer

Answer 2

An API (application programming interface) is a term meaning the functions/methods in a library that you can call to ask it to do things for you - the interface to the library.
A framework is a group of classes, interfaces and other pre-compiled code upon which or by the use of which applications can be built.

Answer 3

but in the end they do same thing that is they have methods, classes, etc and help in making application then is there really a difference?
