C++ Tutorial/set multiset/multiset iterator

iterator that cannot be used to change element values in multiset

<source lang="cpp">#include <iostream> using std::cout; using std::endl;

1. include <set> // multiset class-template definition
2. include <algorithm> // copy algorithm
3. include <iterator> // ostream_iterator

int main() {

  int a[ 10 ] = { 7, 22, 9, 1, 18, 30, 100, 22, 85, 13 };
  std::multiset< int, std::less< int > > intMultiset;
  std::ostream_iterator< int > output( cout, " " );
  intMultiset.insert( 15 );
  intMultiset.insert( 15 );

  // iterator that cannot be used to change element values
  std::multiset< int, std::less< int > >::const_iterator result;
  // find 15 in intMultiset; find returns iterator
  result = intMultiset.find( 15 );
  if ( result != intMultiset.end() ) // if iterator not at end
     cout << "Found value 15\n"; // found search value 15
  cout << endl;
  return 0;
