What are libraries in programming?

In programming, libraries refer to collections of pre-written code that provide a set of functions and routines designed to perform common tasks. Libraries serve as a resource for developers by facilitating code reuse, allowing them to avoid rewriting standard functionalities from scratch. This not only speeds up the development process but also enhances reliability, as these libraries are often tested and optimized for performance.

Libraries can encompass a vast range of functionalities depending on the language and the specific library being used. For example, a math library might include pre-defined functions for various mathematical operations, while a web development library could offer tools for manipulating HTML and sending HTTP requests.

Other options do not accurately define libraries in the context of programming. Tools for managing software licenses pertain more to compliance and ownership aspects of software, while systems for storing database records focus on data management rather than code usage. Frameworks for building user interfaces may include libraries but are broader in scope, as they provide structures and guidelines for developing applications, not just reusable code snippets.
