Difference between array[i] and i[array] Expressions

Answer: We know that we can use pointer and indirection to access an array. Let’s try to rewrite the exp.

    arrays[i];

using pointer as:

    *(arrays + i);

which, of course, we can write as:

    *(i + arrays); /* addition is 'commutative' */

which we rewrite in subscript form as:

        i[arrays];

So, these two expressions are same! But writing this way is awkward and one should practice decent style of programming!
