In computer science, an array is a data structure consisting of a collection of elements (values or variables), of same memory size, each identified by at least one array index or key, a collection of which may be a tuple, known as an index tuple.

Apr 12, 2025 · Array is a linear data structure where all elements are arranged sequentially. It is a collection of elements of same data type stored at contiguous memory locations. For simplicity, we can think of an array as a flight of stairs where on each step is …

Mar 30, 2024 · Learn about Arrays for your A Level Computer Science exam. This revision note includes linear data structures, indexing, and memory allocation.

Arrays are named like variables. The number in brackets determines how many data items the array can hold. The array score (9) would allow ten data items to be stored. Any facility that holds...

Dec 29, 2013 · Arrays are fundamental to computer science. Whether you’re designing video games, optimizing operating systems, or proving algorithms, arrays are essential, fundamental tools.

To assign or read from an array, we simply refer to the array name and index (position) number, e.g. Burger [2] contains “Fillet Tower”. You can use a variable instead of a literal number to represent the index position of an array, with i being a common choice e.g. Burger [i].

Dec 12, 2024 · Arrays are data structures that store a collection of elements in a specific order. They are commonly used to store fixed-size data such as numbers, characters, or strings. On the other hand, linked lists are a dynamic data structure where each element is connected to the next one through pointers.

An array is a data structure that holds a number of data items or elements of the same data type. When you want to store many pieces of data that are related and have the same data type, it is often better to use an array instead of many separate variables.

What Python calls a list would be called an array in most other programming languages. Python also has something different & more advanced called arrays. If you try to ask Python for an index that doesn't exist, it gives you an error: Out-of-range error.

An array is a data framework that is composed of a group of elements. These elements have similar data types, for example all are integers, or all are strings. Learn more about Arrays here!
