Multidimensional Arrays

Grids and jagged arrays.

Beyond a Single Row

So far arrays were a single line of values. A multidimensional array stores values in a grid, like a spreadsheet with rows and columns.

These are great for game boards, tables, and matrices.

A two-dimensional array uses a comma inside the brackets: [,]. You give two sizes, the number of rows and the number of columns.
