Since the interface of the class is part of the class definition in the Time.h header, the client-code programmer must have access to this file and must #include it in the client’s source-code file. When the client code is compiled, the compiler uses the class definition in Time.h to ensure that the main function creates and manipulates objects of class Time correctly.

Please review the material first before take this test. After you start the test you have 30 minutes to complete it. Take the Quiz Again The conventional way to distinguish between the overloaded preincrement and postincrement operators (++) is: Overloading cannot change how an operator works on built-in types.

The operator ___________ reclaims memory previously allocated by new. There exists a data type Date with member function Increment that increments the current Date object by one.

Keyword _______________ introduces an overloaded-operator function definition. The delete [] operator:  Question 13 5 / 5 pts When a unique_ptr goes out of scope, its destructor automatically returns the managed memory to the free store. A unique_ptr is a “smart pointer” for managing dynamically allocated memory. All of the above. You must explicitly delete the memory that’s managed by a unique_ptr before the object goes out of scope. Section 10.9 Dynamic Memory Management  Question 14 5 / 5 pts Otherwise the constructor will only make a copy of a pointer to an object. The copy of the argument passed by value has function scope. The pointer needs to know the address of the original data, not a temporary copy of it. Otherwise infinite recursion occurs. Section 10.10 Case Study: Array Class  Question 15 5 / 5 pts It returns a pointer. It automatically destroys the object after main is exited. It calls the object’s constructor.

The first line of the function definition would be: The prototypes of overloaded cast operator functions do not: [C++11]: To prevent class objects from being copied or assigned, you can: Simply do not declare a copy constructor or assignment operator in the class. Correct Answer Declare as private the class’s copy constructor and overloaded assignment operator or declare the class’s copy constructor and overloaded assignment operator with with = delete after the parameter list.
