Arrays

An array is a systematic arrangement of objects, usually in rows and columns.

The dimensions of an array are identified by the number of rows and columns it contains, typically expressed as 'rows x columns'.

A 5 x 4 array has 5 rows and 4 columns.

A 3 x 4 array has 3 rows and 4 columns.

A 4 x 5 array has 4 rows and 5 columns.

Columns run vertically, from top to bottom.

Rows run horizontally, from left to right.

The total number of elements is 3 rows multiplied by 4 columns, which equals 12.

A 2 x 3 array can be visualized as 2 rows with 3 elements in each row.

The order of dimensions indicates the arrangement of data, affecting how data is accessed and manipulated.
