#include <iostream>
#include <set>
int main()
{
std::set<int> coll; // set container for ints
// insert seven unordered elements with the values 1 to 6
coll.insert(3);
coll.insert(1);
coll.insert(5);
coll.insert(4);
coll.insert(6);
coll.insert(2);
coll.insert(1);
// output all elements followed by a space
std::set<int>::iterator pos;
for (pos = coll.begin(); pos != coll.end(); ++pos) {
std::cout << *pos << ' ';
}
// finally output a newline
std::cout << std::endl;
}
