1-Dimensional Array: IGCSE Computer Science Definition

What is a 1-dimensional array?

In IGCSE Computer Science, a 1-dimensional (1D) array is a structured data type that stores multiple elements of the same data type in a single linear structure. Each element is accessed using an index, starting from 0 in most programming languages.

How is a 1D array used?

1D arrays are commonly used for storing lists of values, such as student scores or sensor readings. They allow efficient data retrieval and modification.

Example in Python:

scores = [12, 10, 5, 2, 8]

print(scores[2]) # Output: 5
