Rectangular array is another type of array that allows you to define a table like array that has a row and column definition.

Syntax:

type[,] = new type[row,column];

type – can be any data type

row – is the number of rows for your table

column – is the number of columns for your table

e.g.

                int[,] mytable = new int[10, 5];
