References (C++) The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com. The latest version of this topic can be found at References (C++). A reference, like a pointer, stores the address of an object that is located elsewhere in memory. Unlike a pointer, a reference after it is initialized cannot be made to refer to a different object or set to null. There are two kinds of references: lvalue references which refer to a named variable and rvalue references which refer to a temporary object. The & operator signifies an lvalue reference and the && operator signifies either an rvalue reference, or a universal reference (either rvalue or lvalue) depending on the context.
