1. Operator overloading is a. giving C++ operators more than they can handle. b. giving new meanings to existing C++ operators. c. making new C++ operators. 2. How many arguments are required in the definition of an overloaded unary operator? 3. Assuming that class X does not use any overloaded operators, write a statement that adds an object of class X, xi, to another such object, x2, and places the result in x3. 4. Assume a class with objects obji, obj2, and obj3. For the statement obj3 - obji - obj2; to work correctly, the overloaded-operator must a. take two arguments. b. return a value. c.create a named temporary object. 5. To convert from a user-defined class to a basic type, you would most likely use a. a built-in conversion operator. b. a one-argument constructor c. a conversion operator that's a member of the class. 6. True or False: The statement obja = obj8; will cause a compiler error if the objects are of different classes. 7. To convert from a basic type to a user-defined class, you would most likely use a. a built-in conversion operator. Page 1 of 4
