CHAPTER 47 — Common Array Algorithms

An array that uses a single subscript is called a one dimensional array. The cells 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.

Chapter Topics:

• 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

In a one dimensional array, the cells are accessed using a single index.
