What do You do when You have to set numer of loops? Usually we do sample like this: variableName= variableName - 1. So we DO one operation more when we starting counting at 0.
I can Youse counting at 0 or 1 but i think that starting counting at 1 is closer for people and decreases implementation bugs.

No - most loops are from start to end, so
int count = GetNumberOfElements();
for (int i=0; i < Count; i++) {} --> 0-based is ok
If you have to loop backwards:
int i = GetNumberOfElements();
while (i--) {} --> 0-based is ok, too

Ok, You're right but if You don't have built in function in some languages....
Ok Klaus, We can decrease count of loops but still we have to remember that some lang. have 0, others 1 index at start. And WEe can write code like yours but if You want to generate grid for customer and each row must be numerated, so You must write row 1, row 2 , not row 0 row 1 etc. So we must read cell from array and ADD +1 (rowNumber+1). If We could write in language where each indexing array would be starting at 1 it could decrease number of bugs and maybe number of operations.

Yes, but try to to revesely:
for(unsigned i=0; i<N; ++i)
a[i]=...;
becomes
for(unsigned i=N-1; i!=0u-1; --i)
a[i]=...
abusing of -1 == MAX_UNSIGNED_INT
or
for(unsigned i=N; i>0; --i)
a[i-1]=...;
for(unsigned i=0, j=N-1; i<N; ++i,--j)
a[j]= ...
asymmetrical, or using cont and indexes as separate concepts.
But if everything start at 1...
for(unsigned i=1; i<=N; ++i) ...;
for(unsigned i=N; i>0; --i) ...;
perfectly symmetrical.
2 bugs found.
> recompile ...
65534 bugs found.

Maybe it is true about the humans. Homo programmicus is a separate species.

I agree. If we were "resetting" the programming industry we should start from 1. But most of us have just gotten used to zero-based indexes so it seems odd now to do anything different.

100% agree. Zero-based arrays and such need to go. Years in the past, a lot of the old BASIC languages gave you a choice. Something on the order of Option1 or Option0 if I remember correctly.
Everybody SHUT UP until I finish my coffee...

Not so "old BASIC". In Visual Basic classic, that is up to VB6, you could specify Option Base 1 at the top of a file for arrays to start at an index of 1.
Even better (or worse, depending on your position), you could define arrays any way you wanted:
Dim x(3 to 10).
Dim y(-20 to 20) that one being very useful to plot coordinates on a graph.
Although they were useful in some applications, those things tended to confuse the non initiated, and forced the initiated to often check the declaration in order to use an array properly.
So I am quite glad that in VB.NET they fixed the basic index of an array.
But since most collections start at 1, why did they not do the same for arrays?

Everything in Computer science and engineering is zeros and ones. The premise of a clock cycle says zero is the start, then one is voltage high, then zero, and so on. I strongly feel they should be zero based.

C and C++ use 0 and I'm fine with that.
Lua uses 1, and that was at first disappointing, now I'm used to and don't bother anymore.
Supporting both (the way VB6 did) still looks a bit weird (but possibly save many 'coders wannabe' from application crashes...).

I'm for '0 or any'. Being fixed at 1 seems arbitrary, being fixed at 0 is completely plausible.

I don't agree, but it is just matter of personal taste.

If you had asked me 25 years ago when I was new to programming I would have said 1. But today I wonder what idiot would want it to start with 0?
Nevertheless, After some deep thought and setting aside my nerdiness, which is compelling me to say 0 (like 90% of other developers) I still believe deep inside that it should be 1. Starting with 0 is still the root of many "off by one" looping errors. Then there are real worldly representations that just do not accept 0 as start and so you are tweaking your index references with in-code "+1" modifications. This happens so much in programming. After decades of programming we are used to it such that starting with 0 seems more natural. But it is not.
Starting with 0 was a first historical step in mankind bowing to the needs of the machines. This will no doubt continue. We are all doomed. Skynet SHALL win. All of you who voted 0 should be aware of the implications of this altered belief of yours. 
Yes. You have become slaves to your machines.

You have opened my eyes.
Now how can I change my vote?

@Shajeel: this is machine era.So mistaken done cant be reverted back. 
always you will get choices as 0 or 1.i m happy that i have voted for 1.

For some things such as color indexing we need 0s to indicate lack of that color. But if we are referencing days of the week, months of the year? Month[0]? Day[0]?
Someone friends have posted strong arguments for 0 base, which (sadly) seem rational to me. But brothers, who am I, but a brainwashed programmer after decades of accepting computer supremacy over my fellow beings? 99.9% of normal humans will not even understand what these friends are talking about! Yes, 90% of us have forsaken our fellow humans in this survey.

I am with Skynet when it all happens any way. This biological hardware with extreme inflexibility to refactoring, and lack of scalability after maturity, is just not the way ahead for evolution.
We need new hardware - as bodies - for intellectual beings. Bodies that can work in a vacuum, can tolerate wider range of temperature, can easily accept exchange of spare parts in case of failure and last but not least, ability to be erased and reprogrammed as the need arises (if only I could erase some of my habits!).
This is the beginning of the end for carbon based, biological hardware.

Array indices are offsets. That's why they start at 0, period.
ar[n] means: addressof(ar) + sizeof(element) * n. This should explain everything. How old are you in years until your first birthday? Right, zero. So your first year is my_life[0].
So according to the results of this survey 10% of the programmers here don't know the basics of mathematics and computers.
Well, at least they read codeproject.

Don't get me wrong, I voted 0 too. But in mathematics, vector indexing (a vector is a 1-dimensional array) starts at 1. Ditto for matrices, which are 2D arrays.

And index? And why there are no multiple choice and free answers?

Alex,
Don't mind these guys. They are not trying to be hurtful.
It is human nature to reflect what is inside and project and super-impose it to what's coming from the outside, to the point that we stop seeing the world as is and see it as we are.
Seems like you are new to programming and this site, and these experienced old-timers did not include that possibility in their calculations. But they mean well. They just did not want non-funny old-timers polluting the site with taste-less comments.
But yours is valid and this site belongs to you. Stick with it. I have learnt a world of programming (and non-programming) knowledge from the guys contributing to this site.
Welcome to Code-Project!
