2 weeks ago - In the C++ programming language, a reference is a simple reference datatype that is less powerful but safer than the pointer type inherited from C. The name C++ reference may cause confusion, as in computer science a reference is a general concept datatype, with pointers and C++ references ...

A reference variable is an alias for an existing variable.

October 4, 2013 - A reference is an alias for another variable. It must therefore be initialized with one the moment it is constructed. It is not possible to make it alias another variable after that.

March 25, 2024 - A reference, like a pointer, stores the address of an object that is located elsewhere in memory. Unlike a pointer, a reference after it's initialized can't be made to refer to a different object or set to null.
