A helper algorithm for random_shuffle() . Shuffles all elements in the container c using uniformly selected random swaps. Uses operator= to perform the swaps.

Declaration


  #include <ospace/helper/helpalgo.h>

template< class Container >
void os_random_shuffle( Container& c )

    #include <iostream>
#include <vector>
#include <ospace/helper.h>

int numbers[ 6 ] = { 1, 2, 3, 4, 5, 6 };

void
main()
  {

  os_random_shuffle( v );

  for ( size_t i = 0; i < v.size(); ++i )
    cout << v[ i ] << ` `;
  cout << "\n";
