assigning a rand number to each element in an array

alright, im trying to write a very simple algorithm that creates a fairly random ID for an object in a binary tree..and heres the basic coding...

Code:

---

  while (x<4) {
          node->bookID[x]=rand()%9+1;
      x++;
  }

---

any clue why it would output 0x008533cc? please, any help would be greatly appreciated. thanks a lot!

perhaps it's incrementing the memory address of the pointer?
i don't know how you have your pointers set up and how and why you have to do certina things, but stripped down to bare bones, heres what i'd do:

Code:

---

int array[4];
for (int i=0; i<4; i++)
{
    array[i]=rand() %11; //0-10
}

---

I also think it's better to use for loops, sinse it's less confusing.
Make sure about the data type of 'x', because it should work...

oops, i was looking at his code and mine at the same time...i edited it now
