Madelung's disease. Common Name(s) Madelung disease is a rare condition characterized by the symmetric growth of fatty tumors (lipomas) around the neck, shoulders, upper arms and/or upper trunk. It most often affects men of Mediterranean ancestry between the ages of 30 and 70 who have a history of alcohol abuse.
Iteration is the act of repeating a process, either to generate an unbounded sequence of outcomes, or with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an iteration, and the results of one iteration are used as the starting point for the next iteration. In the context of mathematics or computer science, iteration (along with the related technique of recursion) is a standard building block of algorithms.
If vector<>::iterator is simply a pointer an initial value NULL should compile (e. g. in VC6). If it is a class type the default constructor of that class will initialize the iterator to a nil value. So, in both cases you have what you want.
