    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.
