Iterating through an `std::unordered_set` in C++ safely and efficiently can be done using different methods depending on the context. Here are some common approaches:
#include <iostream>
#include <unordered_set>
int main() {
std::unordered_set<int> mySet = {1, 2, 3, 4, 5};
// Range-based for loop
for (const auto& element : mySet) {
std::cout << element << " ";
}
std::cout << std::endl;
// Iterator-based for loop
for (auto it = mySet.begin(); it != mySet.end(); ++it) {
std::cout << *it << " ";
}
std::cout << std::endl;
return 0;
}
