An object of type pair. |
_Right |
An object of type pair. |
Remarks
One advantage of swap is that the types of objects that are being stored are determined automatically by the compiler and do not have to be explicitly specified. Don't use explicit template arguments such as swap<int, int>(1, 2) when you use swap because it is unnecessarily verbose and adds complex rvalue reference problems that might cause compilation failure.
