vector insert from a set

[Steven C]

vector <int> vecThe;
set <int> setThe;

vecThe.insert (setThe.begin (), setThe.end ());

This gives an error about iterators not of the right type. Is there a
way around this or do I have to set up a for loop and do
vecThe.push_bac k ()?

However I can do this:

setThe.insert (vecThe.begin (), vecThe.end ());

The vector::insert member function overload that you want
to call actually takes 3 parameters -- the first one being
the position in the vector where the insertion needs to occur:

vecThe.insert(v ecThe.end(), setThe.begin(), setThe.end () );

The alternative is to use the 'assign' function, if you want
to discard any previous contents of the vector:
vecThe.assign( setThe.begin (), setThe.end ());

Yes, set is different since the insertion location
cannot be specified (value ordering is automatically
enforced).

You must specify where to insert. For example:

vecThe.insert (vecThe.begin (), setThe.begin (), setThe.end ());
