The client-code programmer needs to know only Time’s interface to use the class and must be able to link its object code. Correct Answer Often a class’s interface and implementation will be created and compiled by one programmer and used by a separate programmer who implements the client code that uses the class. You Answered To hide the class’s member-function implementation details, the class-implementation programmer would provide the client-code programmer with the header Time.h (which specifies the class’s interface and data members) and the Time object code (i.e., the machine-code instructions that represent Time’s member functions). Section 9.3 Compilation and Linking Process Section 9.3 Compilation and Linking Process  Question 16 5 / 5 pts An object data member is not initialized in the member initialization list.

An error occurs if:  Question 17 5 / 5 pts here this that his 9.14 Using the this Pointer  Question 18 5 / 5 pts You can overload a classes constructors. Just as a constructor can call a class’s other member functions to perform tasks, C++11 allows constructors to call other constructors in the same class. There is no mechanism in C++ for a constructor to call another constructor in the same class. To overload a constructor, provide in the class definition a prototype for each version of the constructor, and provide a separate constructor definition for each overloaded version. Section 9.5 Time Class Case Study: Constructors with Default Arguments  Question 19 5 / 5 pts Both are called automatically, even if they are not explicitly defined in the class. They are both usually called once per object created. They both have the same name aside from the tilde (~) character. An object’s non-static member functions have access to a “self pointer” to the object called the _________ pointer. [C++11]: Which of the following statements is false?

Both first and second choice. Make the copy constructor private. Make the overloaded assignment operator private. Section 10.10 Case Study: Array Class  Question 6 5 / 5 pts "CDEF" "EFGHI" "CD" "EF" Section 10.14 Overloading the Function Call Operator ()  Question 7 5 / 5 pts Another reason why you might choose a non-member function to overload an operator is to enable the operator to be commutative. Operator member functions of a specific class are called (implicitly by the compiler) only when the left operand of a binary operator is specifically an object of that class, or when the single operand of a unary operator is an object of that class. When an operator function is implemented as a member function, the leftmost (or only) operand must be an object (or a reference to an object) of the operator's class. To prevent class objects from being copied: Assume that the function call operator() is overloaded for data type String in the usual sense of selecting a substring from a larger string. For a String object string1 with the character string "ABCDEFGHI", what string does string1(4, 2) return? Which statement is false?  Quiz submitted Based on whether an operator is implemented as a member function or as a non-member function, the operator is used differently in expressions. Section 10.11 Operators as Member Function vs. Non-Member Functions  Question 8 5 / 5 pts operator overloading + overloading + operator reuse operator reuse 10.1 Introduction  Question 9 5 / 5 pts string interpolation. a compilation error a string iterator a string-object literal. Section 10.2 Using the Overloaded Operators of Standard Library Class string  Question 10 5 / 5 pts Suppose a and b are integer variables and we form the sum a + b. Now suppose c and d are floatingpoint variables and we form the sum c + d. The two + operators here are clearly being used for different purposes. This is an example of __________________. [C++14]: The code ", have a great day!"s is an example of ________:  Quiz submitted Class string’s overloaded [] operator returns a vector element as an rvalue or an lvalue, depending on the context. Class string provides bounds checking in its member function at. An exception is thrown if the argument to string’s at member function is an invalid subscript. A string can be defined to store any data type. Section 10.2 Using the Overloaded Operators of Standard Library Class string  Question 11 5 / 5 pts assignment (=), address (&), greater and equal to (=) assignment (=), address (&), comma (,) assignment (=),greater and equal to (=), comma (,) greater and equal to (=), address (&), comma (,) 10.3.2 Operators That You Do Not Have to Overload  Question 12 5 / 5 pts operator:+ operator_+ operator(+) operator+ Section 10.3 Fundamentals of Operator Overloading  Question 13 5 / 5 pts Which of the following is false? To use operators on class objects, they must be overloaded, with the exception of operators ________, __________ and __________. The correct function name for overloading the addition (+) operator is: [C++11]: Which of the following is false?  Quiz submitted To receive a list initializer as an argument to a constructor, you can declare the constructor’s parameter as type list_initialierT where T represents the type of the values in the list initializer. To receive a list initializer as an argument to a constructor, you can declare the constructor’s parameter as type initializer_listT where T represents the type of the values in the list initializer. It’s not possible to pass a list initializer to a constructor. First and third choice. Section 10.10 Case Study: Array Class  Question 14 5 / 5 pts The precedence of an operator cannot be changed by overloading. New operators can never be created. Certain overloaded operators can change the number of arguments they take. Overloading cannot change how an operator works on built-in types. Section 10.3 Fundamentals of Operator Overloading  Question 15 5 / 5 pts Specify a return type. Need to be defined inside the class whose objects are being converted. Specify the type that is being converted. Specify the type they convert to. Section 10.12 Converting between Types  Question 16 5 / 5 pts Take a float as an operand. Be used with linked list classes. Which statement about operator overloading is false? The prototypes of overloaded cast operator functions do not: The array subscript operator [], when overloaded, cannot:  Quiz submitted Take multiple values inside (e.g., [4,8]). Take user-defined objects as operands. Section 10.10 Case Study: Array Class  Question 17 5 / 5 pts The pointer needs to know the address of the original data, not a temporary copy of it. Otherwise infinite recursion occurs. The copy of the argument passed by value has function scope. Otherwise the constructor will only make a copy of a pointer to an object. Section 10.10 Case Study: Array Class  Question 18 5 / 5 pts The left operand is an int. The left most operand must be a class object (or a reference to a class object). The operator returns a reference. The overloaded operator is =. Section 10.4 Overloading Binary Operators  Question 19 5 / 5 pts Simply do not declare a copy constructor or assignment operator in the class. 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. Declare as private the class’s copy constructor and overloaded assignment operator. A copy constructor must receive its argument by reference because: Which situation would require the operator to be overloaded as a non-member function? [C++11]: To prevent class objects from being copied or assigned, you can:  Quiz submitted Declare the class’s copy constructor and overloaded assignment operator with with = delete after the parameter list. Section 10.10 Case Study: Array Class  Question 20 5 / 5 pts Two arrays cannot be meaningfully compared with equality or relational operators. C++ ensures that you cannot “walk off” either end of an array. Arrays cannot be assigned to one another (i.e., array1 = array2;). An entire non-char array cannot be input or output at once.
