State whether the following are true or false. If the answer is false, explain why.

1) The stream member function flags with a long argument sets the flags state variable to its argument and returns its previous value. 2) The stream insertion operator << and the stream extraction operator >> are overloaded to handle all standard data types—including strings and memory addresses (stream insertion only)—and all user-defined data types. 3) The stream member function flags with no arguments resets the stream’s format state. 4) The stream extraction operator >> can be overloaded with an operator function that takes an istream reference and a reference to a user-defined type as arguments and returns an istream reference.
