I have a std::multimap
on which I am iterating using a forward iterator.
std::multimap<int,char>::iterator it;
for(it=map.begin();it!=map.end();++it) {
// do something
}
Now I need to treat the first element differently and start iterating from the second element of the map. How do I do that?
std::multimap<int,char>::iterator it;
for(it = std::next(map.begin()); it != map.end(); ++it) {
// do something
}
This is C++11 only. You'll need to include <iterator>
.
The other option is obvious, but less pretty:
it = map.begin();
++it;
for(; it != map.end(); ++it) {
// do something
}
Take a look at std::advance
, too.
