overloaded

static

True/False: If you overload the prefix ++ operator, the postfix ++ operator is automatically overloaded.

False

True/False: When you overload the << operator, you must also overload the >>operator.

False

True/False: You can overload the conditional operator to make it function as an unconditional operator.

False
