Can someone help me with this constructor?

bigPosInteger::bigPosInteger(int value)
    /*this instructor takes in an integer and constructs it into a bigPosInteger type*/
{ 

   int count=0;
    if(value<0) {
        count =1;
    }
    while(value){
        value /=0;
        count++;
    }
    valueArray= new int[count];

}

I am not sure if I am doing this right. valueArray is a private member function in the class bigPosInteger.
