Arrays are a foundational data structure in programming that allows you to store multiple values under a single variable name. They function as a collection of elements, each identified by an index or a key, which enables efficient access and management of grouped data. For example, if you need to store the scores of students, rather than creating separate variables for each score, you can use an array to hold all the scores in one place. This not only simplifies the code but also makes it easier to perform operations on the entire set of data, such as calculating the average score or sorting the scores in ascending order.

While functions, application management, and code readability relate to programming practices and principles, they do not define the core purpose of arrays. Functions indeed execute code, managing crashes involves error handling techniques, and enhancing readability pertains to writing clear and maintainable code. However, none of these are specifically tied to the functionality that arrays provide in terms of data storage and organization. Therefore, the primary purpose of arrays is clearly reflected in their capability to store multiple values efficiently within a single variable.
