C++ Program to Implement Set_Difference in STL

This C++ Program demonstrates implementation of Set_Difference in STL.

Here is source code of the C++ Program to demonstrate Set_Difference in STL. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

  1. /*
  2.  * C++ Program to Implement Set_Difference in Stl
  3.  */
  4. #include <iostream>
  5. #include <algorithm>
  6. #include <vector>
  7. using namespace std;
  8. int main ()
  9. {
  10.     int first[] = {5,10,15,20,25};
  11.     int second[] = {50,40,30,20,10};
  12.     vector<int> v(10);
  13.     vector<int>::iterator it;
  14.     sort (first, first + 5);
  15.     sort (second, second + 5);
  16.     it = set_difference(first, first + 5, second, second + 5, v.begin());
  17.     v.resize(it - v.begin());
  18.     cout << "The difference has " << (v.size()) << " elements: "<<endl;
  19.     for (it = v.begin(); it != v.end(); ++it)
  20.         cout<< *it<<"  ";
  21.     cout <<endl;
  22.     return 0;
  23. }

$ g++ set_Difference.cpp
$ a.out
The difference has 3 elements: 
5  15  25
