7.8. Multidimensional arrays
You can use
arrays with two dimensions (i.e., subscripts) to represent tables of values consisting of information arranged in rows and columns. To identify a particular table element, we must specify two subscripts—by convention, the first identifies the element’s row and the second identifies the element’s column.
arrays that require two subscripts to identify a particular element are called two-dimensional arrays or 2-D arrays.
arrays with two or more dimensions are known as multidimensional arrays and can have more than two dimensions. Figure 7.19 illustrates a two-dimensional
array contains three rows and four columns, so it’s said to be a 3-by-4
array. In general, an
array with m rows and n columns ...
