-3
#include<iostream.h>

main()
{
int a[10];
return 0;
}

    Because -7 looked silly. Other than that search a little, it's easy to google and there are many identical questions on Stack Overflow. – Denys Séguret Mar 20 '16 at 11:01
  • Why did you write here the code? You need some help with that? – STF Mar 20 '16 at 11:04

  • In some languages, array indices start with 1. See [this question](http://stackoverflow.com/q/1499749/3345375). – jkdev Mar 20 '16 at 11:55

Actually, there is a valid reason. It's because, an array is actually a pointer. So, A[0] means +0 from the beginning (the first position). That's why we use the 0 index.
