1. Two-Dimensional Arrays
Robert Reaves

2. Two-Dimensional Array
Used to represent items in a table with rows and columns, of the same data type.
Good for representing board games, where the screen is though of as a two-dimensional array.
A component in a two-dimensional array is accessed by specifying the row and column indexes of the item.
Think of a map!

4. Array Declaration
DataType ArrayName [ ConstIntExpression ] [ ConstIntExpression ];
Example:
const int NUM_ROWS = 100;
const int NUM_COLS = 9;
float alpha [NUM_ROWS][NUM_COLS];

5. Array Access
To access an individual component of an array, two expressions are used to specify its position.
Array Component Access
ArrayName [ IndexExpression ] [ IndexExpression ];
Example:
alpha[0][5] = 36.4;
