style: for(nth_elem_in_list, end_of_list; next)

Hi,

I'm not very familiar with the std container classes, yet. What's your
favourite style of writing:

std::list<int> li;
std::list<int>::iterator it = li.begin();
std::advance(it, 5);
for( ; it!=li.end(); it++)
...

int main(int argc, char** argv) {printf
("%silto%c%cf%cgl%ssic%ccom%c", "ma", 58, 'g', 64, "ba", 46, 10);}

The only comment I'd make is to prefer ++it to it++. it++ has to do more
work than ++it (because it must save and return the old value of the
iterator as well as incrementing the iterator), so ++it may be more
efficient and is just a easy to type and understand.
