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... rp
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
Wikipedia: Ada Lovelace, (1815 - 1852) was an English mathematician and writer chiefly known for her work on Charles Babbage's proposed mechanical general-purpose computer, the Analytical Engine. She was the first to recognise that the machine had applications beyond pure calculation. My words: Ada is acclaimed as the first person to program a machine/computer. Also recognise that a machine can be programmed for different purposes. She therefore invented the first programming language for her own use. she created and published the first computer algorithm... Astonishing!
Interesting question. From the programmer's point of view, that depends on how you nest your loops. Behind the scenes, it depends on the programming language. This should help th-cam.com/video/oWM7fjaiWw0/w-d-xo.html :)KD
There is no built in multi-column combobox available. There are however a number of websites that explain how you can create one. You could also use a datagrid control. Sorry I'm not much help right now but this is something I could cover one day in my advanced course. :)KD
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.
Absolutely right. If you think of a 2D array as a table, it's up to you what you store in the columns and what you store in the rows. It's also purely arbitrary what you call 'x' and what you call 'y' (if at all). Behind the scenes it's quite different. You might find this interesting th-cam.com/video/oWM7fjaiWw0/w-d-xo.html :)KD
Take a look at the way that the array is declared: Columns first and then Rows. "Obama" is in Column 1 and Row 0 so its reference co-ordinates will be 1,0

Delighted to help. I will be making some more VB videos soon. :)KD
Very helpful, as always, for my students
Good video
Thank you :)KD
You make it easy to understand and thanks for the table layout. Very helpful. Appreciate all you're doing...Thanks so much.....jt

very helpful course. Thank you.
You're most welcome. :)KD
Thank you for the video, it was very helpful :-)
You're welcome :)KD
I have a question
does it indexes rows first then column?

So, VB is a row major programming language. Thank you! :D
How would i display the mult dimensional array into a list box in the format of (x,y)?
