Arrays - Single and Two Dimensional
Arrays store multiple values of the same type, with single-dimensional arrays being lists and two-dimensional arrays being grids (like table
Core concept
A single-dimensional array stores a list of values, accessed using an index, like numbers[0] for the first element.
How it works
A two-dimensional array stores data in rows and columns, like a grid or table, accessed using two indices, like grid[0][1].
Why it matters
Arrays are useful for storing collections of related data, like a list of student marks or a grid representing a game board.
Key detail
Understanding arrays helps us efficiently store, access, and manipulate multiple related values in a program.
