31.1.2.Use std::make_heap to create heap from a vector
#include <iostream>
using std::cout;
using std::endl;

#include <algorithm>
#include <vector>
#include <iterator>

int main()
{
   int a10 310527722311981340 };
   std::vector< int > va, a + 10 )// copy of a
   std::vector< int > v2;
   std::ostream_iterator< int > outputcout, " " );

   std::copyv.begin(), v.end(), output );

   std::make_heapv.begin(), v.end() )// create heap from vector v
   cout << "\n\n";

   std::copyv.begin(), v.end(), output );
