Set_Symmetric_difference in C++ STL

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

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

$ g++ set_Symmetric_difference.cpp
$ a.out
The symmetric difference has 6 elements: 
5  15  25  30  40  50
