Your 'i' will only have a value of 0, the first time the outer loop is run, in the example on the page, it is initiated to 0 on each run.

/* n is a straight up integer */
j = 0;
while(n) {
      i = 0;
      do {
            j = ( j + state[i] + state2[i] );
            x = state[i];
            state[i] = state[j];
            state[j] = x;
            i++;
      } while (i);
      n--;
}
