Category: Arrays

An array is a data structure that stores a collection of items. These items can be of the same data type (such as an array of integers) or they can be of different data types (such as an array of strings and integers).

Arrays are useful for storing and organizing data in a structured way, and they are often used in programming languages to store lists of items. They are particularly useful when you need to store and access large amounts of data efficiently, as they allow you to access specific items in the array quickly by using an index.

Arrays can be either one-dimensional (also known as a “vector”) or multi-dimensional (such as a two-dimensional “matrix”). In a one-dimensional array, the items are stored in a linear sequence, and each item is identified by a single index. In a multi-dimensional array, the items are stored in a grid-like structure, and each item is identified by a pair of indices.

Some common operations that can be performed on arrays include adding and removing items, searching for specific items, and sorting the items in the array.

Overall, arrays are a powerful and versatile data structure that are widely used in computer science and programming.
