      What is The Difference Between Reference and Pointer in C++?


    • #56186

      Reference

      1) A reference variable is a different name for an existing variable. If the variable initialized the variable name can be used to refer to a different variable.

      2) Reference works like an alias for an existing variable. It is a temporary variable.

      3) It does not need any indirection operator to access the value.

      4) A null value cannot be assigned to the reference variable.

      Pointer

      1) A pointer is a variable that holds the memory address of another variable.

      2) Pointer variable needs an indirection operator to access the value of a variable.

      3) A null value can be assigned to the reference variable.
