An array that uses a single subscript is called a
**one dimensional** array.
The slots of the array can be thought of as
lined up one after the other in a line.
Two dimensional arrays, three dimensional arrays, and
higher dimensional arrays also exist.
This chapter discusses typical ways
in which one dimensional arrays are used.

- Arrays and counting loops.
- The length of an array.
- Finding the maximum and minimum of a numeric array.
- Finding the sum of the elements of an array.
- Computing the average of the elements of an array.

The slots of an array are often called **elements**.
In a one dimensional array, the elements are accessed using
a single index.
