//I think this is a better way for a for loop
//for like going through arrays or something
//hope you like it :)
//be sure to do #include <set>
int main()

for (auto itr = letters.begin(); itr != letters.end(); ++itr){

for (auto&& [first,second] : mymap) {
// use first and second
}for(auto x: myVector){
