CHAPTER 47 — Common Array Algorithms

An array that uses a single subscript is called a one dimensional array. This is because one index is used to access the values in the array. Its cells are like boxes lined up one after the other in a line. A two dimensional array requires two indexes to access values. Its cells are like boxes arranged into a rectangle. Arrays of even higher dimension are possible, although rarely used. This chapter discusses typical uses for one dimensional arrays.
