Visual Basic.NET Programming. Beginner Lesson 21. 2D Arrays & Nested Loops

This is the twenty first 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 extract data from a two dimensional array using nested loops. A two dimensional array, also referred to as a 2D array, is typically used to store and process related groups of data items, and can therefore be visualised as a table with rows and columns. You will learn how to scan a 2D array, either row wise or column wise, and how to build a single output string using data items from a 2D array. You will also see how a 2D array can be searched.
