Thanks. Pat

It the sort of operation the STL is tailor made for

#include <vector>
#include <algorithm>
#include <functional>
#include <iostream>
#include <iterator>
using namespace std;

int main()
{
int data[10] = { 1, 2, 6, 2, 4, 6, 3, 1, 4, 5 };
vector<int> v(data, data + 10);

// remove all elements greater than 3
v.erase(remove_if(v.begin(), v.end(), bind2nd(greater<int>(), 3)),
v.end());

copy(v.begin(), v.end(), ostream_iterator<int>(cout, " "));
cout << '\n';
}
