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.

    it = set_symmetric_difference(f, f + 5, s, s + 5, v.begin());

```
    v.resize(it - v.begin());
```

    cout<<"The symmetric difference has "<< (v.size())<< " elements: "<<endl;

    for (it = v.begin(); it != v.end(); ++it)

```
        cout<< *it<<"  ";
```
```
    cout <<endl;
```
```
    return 0;
```
```
}
```

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