Why the array size in programming language start with 0 and not with 1 or any other number. what will be if it will start from any other number?
Dear Issac
I think this is not in the way you are putting in. This is not the matter of compiler. you can see that every language use the starting of array with 0. also in the theory we use the array start with 0 where no computer is there. programming languages like c, c++ , java, C# or even in .net array start with 0. There will be some logic behind this. i think you should try to find out that. programming languages and also compiler are made by human. and there must be some logic behind this. please try to find out i am sure you will be succeed.
Profound question.
Well, to put it simply, this question is like asking why "one" is called "one" and not "two". Which is also profound.
The answer? That was the way it is generally set by the designer of the COMPILER of the programming language. What I think is that since zero is a number as well, we can start with that.
In XML though, when you want to access nodes, the specification says that those who implement XML processors (like those built into IE, Firefox, Chrome, etc) should start the numbering of nodes from "1".
However, MS chose to implement the index of the first node as zero and NOT one.
So, I hope you can see that there is no logic, it is just a matter of choice.
As to what will happen if it starts with any other number... nothing! All we have to do is know the starting index number and we can take it from there.
