combining two stl vectors

Hi,

I am trying to combine two stl vectors into one

so something like

std::vector<int> vector1;
std::vector<int> vector2;
std::vector<int> FullVector;


so that FullVector = vector1 + vector2


Is there any other better way than using a for loop?

FullVector.reserve(vector1.size() + vector2.size()); // Optional, tiny
performance improvement

FullVector.insert(FullVector.end(), vector1.begin(), vector1.end()); //
insert the first vector
FullVector.insert(FullVector.end(), vector2.begin(), vector2.end()); //
insert the second.

#include <vector>
#include <iterator>

int main( )
{
typedef std::vector< int > V;

V vector1;
V vector2;
V fullvector;

std::back_insert_iterator< V > p( fullvector );

copy( vector1.begin( ), vector1.end( ), p );
copy( vector2.begin( ), vector2.end( ), p );
}
