Is something like this is possible or there is any way to assign the pair values separately in for loop?
vector<pair<int, int>> arr;
// Input some values here in arr
for(auto &[x,y]: arr){
cout<<x<<" "<<y;
}

5Your code [compiles](https://wandbox.org/permlink/g3SVc9AcrJQtQ7GM) as C++17. – MikeCAT Oct 23 '20 at 17:43

1@πάνταῥεῖ This uses structured bindings: https://en.cppreference.com/w/cpp/language/structured_binding . It should compile in C++17. – Anonymous1847 Oct 23 '20 at 17:46

@MikeCAT Thanks. I got it. I have seen like this in someone else's code but in my version it was getting me error. Now I have to change to C++17. – Shantanu Tripathi Oct 23 '20 at 17:46

@MikeCAT Add answer? – Anonymous1847 Oct 23 '20 at 17:49

@Anonymous1847 I won't because I don't know C++17 and I just found this by seeing compiler message. You can add answer. – MikeCAT Oct 23 '20 at 17:52

Your code is actually valid code in C++17 or later, as @MikeCAT said. You're using what's called a structured binding. It can unpack values from arrays or simple class types, in this case from pairs.
