24.24.4.Copy only unique elements in a vector into another vector
#include <iostream>
using std::cout;
using std::endl;

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

int main()
{
   const int SIZE = 10;
   int a1SIZE 135791357};
   std::vector< int > v1a1, a1 + SIZE )// copy of a
   std::ostream_iterator< int > outputcout, " " );

   cout << "Vector v1 contains: ";
   std::copyv1.begin(), v1.end(), output );

   std::vector< int > results1;

   std::unique_copyv1.begin(), v1.end(), std::back_inserterresults1 ) );
   cout << "\nAfter unique_copy results1 contains: ";
   std::copyresults1.begin(), results1.end(), output );

   return 0;
}
Vector v1 contains: 1 3 5 7 9 1 3 5 7 9
After unique_copy results1 contains: 1 3 5 7 9 1 3 5 7 9
24.24.unique copy
24.24.1.Remove adjacent duplicates: unique_copy
24.24.2.Read all characters while compressing whitespaces
24.24.3.Use unique_copy to copy elements in an array to list with back_inserter
24.24.4.Copy only unique elements in a vector into another vector
24.24.5.Use unique_copy to print elements with consecutive duplicates removed
24.24.6.Use unique_copy to print elements without consecutive entries that differ by one
24.24.7.Copy standard input to standard output while compressing spaces
