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.

Your tutorials on visual basic is the sole reason that I haven't failed my computer science class yet. That and my professor is willing to work with me after I've figured out like 70% of what I'm doing

I just started a C# boo camp and after regular arrays, we are learning 2d arrays. Since the beginning of the week, I've watched about 12 videos trying to understand them, but none has made it so easy to see the logic as you and I thank you for the knowledge.
You turned the light on and now I can see how to handle them...
Muchas gracias...

Very helpful, as always, for my students

You make it easy to understand and thanks for the table layout. Very helpful. Appreciate all you're doing...Thanks so

How would i display the mult dimensional array into a list box in the format of (x, y)?

[brylemacasuhot]

I have a question
does it indexes rows first then column?

[mikewade]

Okay, I admit to being confused at first. It seems to me that "Obama" is in (0, 1) rather than (1, 0) and "Male" is in (0, 2). Is it only a matter or perspective? I'll code a bit to see.
