I would take it as a[9], a[19], ... yes.
When you mark every tenth man in a line, you count them "one, two, ... nine, YOU, one, two, ..."
I wouldn't count the first one, just the tenth.

If you are asked to list every tenth year of this century, would you list 2009, 2019, ... ?
|
|
|
|
|
A century has an unambiguous starting point, so 2010 and 2020 would be correct. This would indeed be [9] and [19] if [0]=2001.

Um, no. There was no year zero, so year 100 was the end of the first centry, 101 the beginning of the second century, etc.
|
|

|

Yes, and so 2001 was the beginning of the 21st century, with 2010 being its 10th year.

Yes there was. It was the year just before year 1. If C, C+=, C# programmers were around then (who knows?), then there was a Year 0. If there were only VB programmers then there wasn't.

The Church disagees. 1BC was followed by 1AD. There was no 0BC/8AD inbetween.
This has been recognized by historicans for decennies, maybe centuries. Today, it is also recognized by all (serious) developers of computer software handling historic data, hereunder genealogical information.
Enjoy it or hate it - your choice! In our office building, our elevator goes directly from floor 1 to floor -1. For our mental comfort, we declared that there is in fact a floor 0 inbetween them, but it is virtual. And since it is virtual, the elevator operating in real space cannot make a stop in virtual space - that is why it skips directly from 1 to -1.
We have learned to live with it. Similarly, you will have to learn with years skipping directly from -1 to 1 without a stop at 0.

Let it be noted that in civilized countries, the ground floor is floor number zero.
|

You also have ground floors. The floors in uncivilized countries are not the ground, it is raised from the ground, usually by a either a layer of concrete or wooden beams, and then a layer of planks above that, usually topped by tiles, carpeting or e.g. a vinyl cover. We prefer that, compared to walking directly on the ground ... even if it less civilized.

VB arrays have an 0th element by default. It's just ignored/skipped by many programmers. The confusion of caused that the DIM statement doesn't actually give the dimension (as the equivalent in C/C++/C# does), but instead the upper limit.

Your option 1 is precisely how I interpret the question. I could understand forgetting to start the index at 0 (getting some of #2), but printing the first index regardless is incorrect.
|
|
|
|

I don't think it's a question of English. "Every 10th number" is clear, but where to start means making an assumption. If stated in another language that I can read, I would feel the same way.

I am not making any assumption. I am starting from the beginning of the array.

Don't you mean zeroth, tenth, etc?

From what base?
Yet another poorly-worded spec. You definitely need to know which element to start with. It should at least be something along the lines of, "starting with element n, select every mth element".
To cover the variants I can think of at the moment, I would write a method which takes three parameters: the index of the first element to select, how many elements to select from that position, and the number of elements to skip to get to the next element to select.

The ID of the first element of the array is irrelevant.
If you have an array that starts with an element identified as a(47), then the tenth element is a(56).

 This explanation makes sense also for a protozoon like me.

So you consider element 47 not as the first one.
The ninth element is #55, the eigth is #54... the 1st is #48, the 0th is #47. Fair enough, from a programmer point of view. Your grandmother might disaggree. But as we all know: Today, computer guys rule the world.
In sports games, we still rank the competitors as "1st place", "2nd place" and "3rd place". As soon as computer guys succeed in taking over sports, it most surelu will be changed to "0th place", "1st place" and "2nd place"...

I think you must have misread. Element a(47) is the first element.
Treat the "a(47)" as an identifier (which is precisely what it is) and not as something to do with its cardinality.
It's like you can have variables named 'a', 'b', and 'c', but those names/identifiers have nothing to do with the order they're used in, their importance, etc.
"An array element by any other name would still be in the same cardinal position" -- Wm. Shakespeare, who predicted the existence of arrays centuries before computers were built.

I agree.
Let's say you're instructed to "get on the highway headed east and drive to the second exit". You don't count the interchange you enter at. Nor do you consider where "exit 2" might be -- you may have entered at exit 2, or it may be to your west.
So "every tenth" has nothing to with how the elements may be indexed, only with which order they're encountered in.
For that matter, does it matter if an array cell is empty? Would those count?

Sure. If a hotel clerk has to check the tenth pigeonhole from the left for mail, he doesn't skip the empty ones.
