how to iterate on elements of a set in cpp code example

Example 1: iterating a set c++

//Given set s
for(auto it: s){
	cout << it << endl;
}

Example 2: loop through set c++

// set::begin/end
#include <iostream>
#include <set>

int main ()
{
  int myints[] = {75,23,65,42,13};
  std::set<int> myset (myints,myints+5);

  std::cout << "myset contains:";
  for (std::set<int>::iterator it=myset.begin(); it!=myset.end(); ++it)
    std::cout << ' ' << *it;

  std::cout << '\n';

  return 0;
}
