C++ Static Data Interview Question:
What is reference variable in C++?
Submitted by: AdministratorA reference variable is just like pointer with few differences. It is declared using & operator. A reference variable must always be initialized. The reference variable once defined to refer to a variable can't be changed to point to other variable. You can't create an array of references the way it is possible with pointer.
