Tweet Share WhatsApp

Answer:

When a reference is created, it can’t reference another object. This can be done with pointers. References cannot be null whereas pointers can be. References cannot be uninitialized and it is not possible to refer directly to a reference object after it is defined.

Example:
Syntax of reference:
<Type> & <Name>
int& rA = A; rA is a reference to int.
