Web Reference: Nov 11, 2024 · In C++, a reference is an alias for an existing object. Once a reference has been defined, any operation on the reference is applied to the object being referenced. This means we can use a reference to read or modify the object being referenced. Jul 26, 2025 · In C++, functions can return references to variables. This is especially useful when you need to return large data structures or want to allow direct modifications to a variable inside a function. 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.
