8.9 Multidimensional Arrays

Two-dimensional arrays are often used to represent tables of values consisting of information arranged in rows and columns. To identify a particular table element, we must specify two indices. By convention, the first identifies the element’s row and the second its column. (Multidimensional arrays can have more than two dimensions, but such arrays are beyond the scope of this book.) C# supports two types of two-dimensional arrays—rectangular arrays and jagged arrays.

8.9.1 Rectangular Arrays

Rectangular arrays are used to represent tables of information in the form of rows and columns, where each row has the same number of columns. Figure 8.17 illustrates a rectangular array named a containing three rows and four ...
