};


int main()

    Cell *c = NULL;
    Cell *HEAD = NULL;
    
    srand (time(NULL));

    for (int i=0; i<MAX; i++) {
        // Use dynamic memory allocation to create a new Cell then initialize the 
        // cell value (val) to rand().  Set the next pointer to the HEAD and 
        // then update HEAD.
