What is the primary function of a library in programming?

To provide reusable code modules that save development time

The primary function of a library in programming is to provide reusable code modules that save development time. Libraries are collections of pre-written code that developers can use to perform common tasks without having to write everything from scratch. This modularity enables faster development, as programmers can leverage established functions and features, test them, and integrate them into their applications.

By using libraries, developers can access and implement complex functionalities—such as manipulating data structures, handling network requests, or performing mathematical computations—simply by calling the relevant library functions. This approach not only accelerates the development process but also encourages code reuse, consistency, and collaboration within software projects.

This option stands out primarily for its focus on efficiency and ease of coding, which are key benefits of utilizing libraries in programming.
