The set_symmetric_difference() function of C++

[Gavyn]

I am interested in doing the programming. Thus, I had just started for learning the C++ programming language. I can also have the knowledge of the basic working of the functions. Hence, I want to know what is the set_symmetric_difference() function of the C++ language. I also want to know what is the use of the set_symmetric_difference() function in the C++ programming. Can anyone knows about the set_symmetric_difference() function of C++ language.

The set_symmetric_difference() function of the C++ language can be used for the difference that can be symmetric of the two given specified ranges that can be sorted. The set_symmetric_difference() function can constructs a sorted range that can be starting in the place that can be pointed by the rslt with the set of difference that can be symmetric of the two given specified ranges such as the range [fst1,lst1) and the range [fst2,lst2) that can be sorted as content. The set_symmetric_difference() function can be comes under the algorithm header files.

The set_symmetric_difference() function of the C++ language can be used to create the symmetric difference between the two given ranges. The following can be the general form of the set_symmetric_difference() function in the C++ language :

template <class InptItrtr1, class InptItrtr2, class OtptItrtr>
  OtptItrtr
    set_symmetric_difference ( InptItrtr1 fst1, InptItrtr1 lst1,
                               InptItrtr2 fst2, InptItrtr2 lst2,
                               OtptItrtr rslt );

The following program can demonstrates you how to implement the set_symmetric_difference() function of the C++ language in the C++ programming as follows :

#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
int main () 
{
  int ft[] = {5,10,15,20,25};
  int sd[] = {50,40,30,20,10};
  vector<int> v(10);    
  vector<int>::iterator i;
  sort (ft,ft+5);    
  sort (sd,sd+5);
  i=set_symmetric_difference (ft, ft+5, sd, sd+5, q.begin());
  cout << "symmetric difference has " << int(i - q.begin()) << " elements.\n";
  return 0;
}

Output:

symmetric difference has 6 elements

[Zecho]

The following can be the parameters of the set_symmetric_difference() function in the C++ language :
1. fst2, lst2 : These parameters of the set_symmetric_difference() function can contains an input iterators to the final and starting positions of the given second sequence. The range used can be as [fst2,lst2).
2. fst1, lst1 : These parameters of the set_symmetric_difference() function can contains input iterators to the final and starting positions of the given first sequence. The range used can be as [fst1,lst1) that can contains all of an elements that can be between fst1 and lst1.

PROGRAM :

     #include<algorithm>
     #include<set>
     #include <istream.h>
     using namespace std;
     int main()
      {
     int B1[] = {1,3,5,7,9,11};
     int B3[] = {3,5,7,8};
     set<int, less<int> > od(B1+0,B1+6), rslt,
        small(B3+0,B3+4);
     insert_iterator<set<int, less<int> > >
        res_ins(rslt, rslt.begin());
     cout << "The symmetric difference of:" << endl << "{";
     copy(small.begin(),small.end(),
         ostream_iterator<int,char>(cout," "));
     cout << "} with {";
     copy(od.begin(),od.end(),
         ostream_iterator<int,char>(cout," "));
     cout << "} =" << endl << "{";
     set_symmetric_difference(small.begin(), small.end(),
                             od.begin(), od.end(), res_ins);
     copy(rslt.begin(),rslt.end(),
         ostream_iterator<int,char>(cout," "));
     cout << "}" << endl << endl;
     return 0;
      }

Program Output :

     The symmetric difference of:
     {3 5 7 8 } with {1 3 5 7 9 11 } =
     {1 8 9 11 }
