    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...
    none...
