iterating in set in c++ code example

Example 1: iterating a set c++

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

Example 2: iterate over a set in C++

//Method 1
 // Iterate over all elements of set
 // using range based for loop
 for (auto& i : mySet)
 {
    cout << i << " , ";
 }

//Method 2
 // Iterate over all elements using for_each
 // and lambda function
 for_each(mySet.begin(), mySet.end(), [](const auto & str)
 {
    cout<<str<<", ";
 });

//Method 3
 set<string>::iterator it = mySet.begin();
 // Iterate till the end of set
 while (it != mySet.end())
 {
    // Print the element
    cout << *it << ", ";
    //Increment the iterator
    it++;
 }
