Visual Basic.NET Programming. Beginner Lesson 20. Two Dimensional Arrays
This is the twentieth in a series of computer science video tutorials for beginners, about programming with Visual Basic.NET (VB.NET) in Visual Studio. In this lesson you will learn how to declare and initialise a two dimensional array variable. A two dimensional array, also referred to as a 2D array, is typically used to store and process related groups of data items. This video emphasises the importance of visualisation when it comes to working with 2D arrays; a 2D array can be visualised as a table with rows and columns. You will also learn how to output individual data items from a 2D array, by means of row and column references, and how to output an entire row or an entire column by means of a looping constructs. The next video of this series explains how to manipulate a 2D array with nested loops.
