Libraries and frameworks are both tools used in software development, but they serve different purposes.

Library

A library is a collection of pre-written code that you can use in your own programs. You can call functions from a library to perform specific tasks without having to write that code yourself. Libraries are typically more focused and allow you to pick and choose which parts to use in your project.

Framework

A framework is a more comprehensive tool that provides a structure for your application. It usually dictates the flow of control, and you build your application within the framework's structure. Frameworks often provide a set of rules and guidelines that you need to follow while developing your application.

Libraries give you more flexibility as you can use them for specific tasks, while frameworks provide a more structured environment for developing your application.
