// C++ Program to illustrate how to delete multiple elements
// from a set
#include <iostream>
#include <set>
using namespace std;

int main()
{
    // Set and elements to be deleted from a set
    set<int> s = { 10, 20, 30, 40, 50, 60 };
    set<int> elements_to_delete = { 20, 30, 40 };

    // Print the original set
    cout << "Original set: ";
    for (auto it = s.begin(); it != s.end(); ++it)
        cout << *it << " ";
    cout << endl;

    // Delete elements from the set
    for (auto it = elements_to_delete.begin();
         it != elements_to_delete.end(); ++it)
        s.erase(*it);

    // Print the set after deletion
    cout << "Set after deletion: ";
    for (auto it = s.begin(); it != s.end(); ++it)
        cout << *it << " ";
    cout << endl;
