Array: IGCSE Computer Science Definition

What is an array?

In IGCSE Computer Science, an array is a fixed-size data structure that stores multiple values of the same data type in contiguous memory locations. Arrays can be one-dimensional (1D) or multi-dimensional (2D, 3D, etc.).

Why use arrays?

Arrays allow efficient storage and retrieval of data, making them useful for storing lists, tables, and matrices in programming.

Example in Python:

numbers = [10, 20, 30, 40]

print(numbers[1]) # Output: 20
