std::remove_copy is an algorithm to copy a container, thereby removing an element value.


#include <algorithm>

#include <cassert>

#include <vector>



int main()

{

  std::vector<int> v;

  v.push_back(0);

  v.push_back(1);

  v.push_back(2);



  std::vector<int> w;



  //copy v to w, removing values of 1

  std::remove_copy(v.begin(),v.end(),std::back_inserter(w),1);



  assert(v.size() == 3);

  assert(v[0] == 0);

  assert(v[1] == 1);

  assert(v[2] == 2);



  assert(w.size() == 2);

  assert(w[0] == 0);

  assert(w[1] == 2);

}
