Names (cont)

A trade-off with names:
  • very long names hide program structure 

    sumOfValues = 0;
for (currentElement = startOfList;
     currentElement != NULL;
     currentElement = currentElement->next) {
     sumOfValues += currentElement->value;
}

  • very short names hide meaning 

    s = 0;
for (p = l; p != NULL; p->n)
    s += p->v;
