#include<conio.h>
#include<stdio.h>
void main()
{
    int i=0;
    char s[]={"this is string"};
    while(s[i]!=0)
    {
        printf("%c",i[s]);
        i++;
    }
}

This Program does not give error and produce output as "this is string". why..??

`s[i]` and `i[s]` are same as `*(s + i)`. – BLUEPIXY Apr 27 '17 at 11:39

Short answer: don't write weird crap like that and you don't have to worry about why it works. Knowing that you can change the place of the `s` and `i` is useless knowledge. – Lundin Apr 27 '17 at 11:49
Please format your code (like in your C textbook). – Jabberwocky Apr 27 '17 at 12:20
