Re: STL iterator question

In my little program I am using a set<vector<int> > rather than a
vector<vector<int> > because the program produces many duplicates, and
the set seems to be just the right type of container to keep them out.

I'm having trouble sending the contents of the set to my screen or to a
file - don't know how to refer correctly to the integers in the vectors:

set<vector<int> > svint;
vector<int> vint;
.
.
svint.insert (vint); etc.
.
.
for (set<vector<int> >::iterator svi = svint.begin();
svi != svint.end(); ++svi)
{

for (vector<int>::iterator vi = ?; vi != ?; ++vi)

cout << ? << " ";

cout << endl;
}

I know that in a vector<int> you can refer to the elements by using *vi,
but I don't know how to proceed now that the vectors are embedded in a
std::set. All help appreciated!
