How do I use iterators with std::set in C++17?

Can you explain how to use iterators with std::set in C++17?

Sure! In C++17, you can use iterators with std::set to traverse elements. You can use both begin() and end() methods to get iterators.

What are the differences between begin() and cbegin()?

The begin() method returns an iterator that allows modification of the elements, while cbegin() returns a constant iterator, which does not allow modifications.

Can you show me a code example?

Absolutely! Here's a simple example:

#include <set>
#include <iostream>

int main() {
    std::set<int> mySet = {1, 2, 3, 4, 5};
    for (auto it = mySet.begin(); it != mySet.end(); ++it) {
        std::cout << *it << " ";
    }
    return 0;
}

What happens if I try to modify an element using an iterator?

If you try to modify an element using a non-const iterator, it will work. However, modifying elements in a std::set is not allowed since it would violate the set's properties.
