+Pair is a container class in CPP defined in <utility> header file. It consists of two elements.
+
+You can access the first element as 'first' and second element as 'second'. They both can be of any data type. (This class is made using templates)
+
+We can use the pair class where we need to store two properties like when finding diameter of a binary tree.
+
+This is the inbuilt version, we can create our own version too.
