Data type in List stl

#1

in list class what is the data type of iterator
for(auto it = l.begin();it!=l.end();it++)
{
cout<<*it<<endl;
}

#2

it depends on datatype that iterator is iterating eg , for list iterator it should be list::iterator, for map it should be map::iterator ,for set it is set::iterator, they are kind of smart pointer but there are several classifications inside iterators itself , if you want to dig in deep then i would suggest you to refer this :-
