Thread: count how many time the value appear in the link list -- HELP

if you must keep the return type void can you change the parameter list to include a reference to int, ie:

Code:

void IPlist::updateCount(string address, int &count)
// precondition : address is in list
// postcondition : the count of node with address has been incremented
{
    count = 0;
    node *tmp = list;
    while(tmp != NULL && tmp->IPaddress == address)
    {
        count++;
        tmp = tmp->link;
    }
}
