How to redefine a pair in c++

Question

I am working a lot with pairs in c++ these days so I want to do next:

Instead of:

pair<int, int> p;
cin >> p.first >> p.second;

I want to write:

pair<int, int> p;
cin >> p.x >> p.y;

I tried #define first x and similar things but it doesn't work. How to redefine this?

Just define your own template struct with x and y members. Just like std::pair, just with different member names. Then use your own struct instead of std::pair.

Or just `struct point { int x, y }; point p;`. – melpomene Jul 28 '18 at 18:24
@melpomene assuming the types are always `int`. A template gives more flexibility and matches `std::pair` closer. – Jesper Juhl Jul 28 '18 at 18:27
