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.
