how to loop through an array and jump back to beginning

[drhinri]

I'm trying to write a program and part of it is stumping me. I have an array of seven integers. The default value of each is 0. Some have other values though. Here's my issue. When the element is 0, i want to replace the value with x. For example, if array[1] = 0, then x would go into array[1]. So, if array[1] != 0, then i want to put "x" into the next xth element, if that next element is 0. So if x was 3, array[1]!=0 so then it checks array[3]. array[3] =0, so x goes into array[3]. heres my question. it checks array[3], and it !=0, so i go to the next xth element, which is array[6] in this case. array[6]!=0. now i want to go to the next xth element, but there are no elements, so i want to loop back around to the beginning, starting at array[0]. so the next comparison it would make would be at array[2]. how do i write a loop like this? in order to find the zero, it checks every xth element through the array, looping around until it finds a zero. there is guaranteed to be a zero somewhere.
thanks a bunch.

Use a while loop instead.

while not finished {
    if array element is 0 {
        change array element
        update x
        if x is greater than length {
            reset back to zero (or what ever)
        }
    }
    determine if finished
}

      for(int i=0;i<array.length;i++){
             if(array[i]==0){
                 //....update code
             }
      }

You could but it wouldn't do what the OP wants.
