Where Does a Reference Live? Understanding Address Attribution in C

Uncovering the Location of References: Demystifying Address Attribution

Despite their intricate relationship with variables, references remain entities unto themselves, devoid of their own addresses. This fundamental distinction stems from their very nature, which differs markedly from pointers.

Unlike pointers that carry the address of another variable, references establish an inseparable bond with the object they are initialized with. Once this connection is forged, the reference becomes synonymous with its referent. This inseparable bond means that references lack the ability to be reassigned to a new object.

The C FAQ provides an insightful explanation of this concept:

"Unlike a pointer, once a reference is bound to an object, it can not be 'reseated' to another object... [remember:] the reference is its referent."

Therefore, attempting to obtain the address of a reference ultimately leads to the address of the referent itself. This behavior emphasizes that the reference is not an independent entity but rather an extension of the object it represents. For a deeper understanding of the nuances between references and pointers, refer to our comprehensive analysis.
