Exam 10: Operator Overloading; String and Array Objects

Y and z are user-defined objects and the += operator is an overloaded member function. The operator is overloaded such that y += z adds z and y, then stores the result in y. Which of the following expressions is always equivalent to y += z?

Which of the following is not a disadvantage of default memberwise copy with objects containing pointers?

Because the postfix increment operator returns objects by value and the prefix increment operator returns objects by reference:

For operators overloaded as non-static member functions:

Which of the following is false?

Which of the following lines would be the prototype for an overloaded cast operator function that converts an object of user-defined type Time into a double?

To prevent class objects from being copied or assigned, you can:

There exists a data type Date with member function Increment that increments the current Date object by one. The ++ operator is being overloaded to postincrement an object of type Date. Select the correct implementation:

An overloaded + operator takes a class object and a double as operands. For it to be commutative (i.e., a + b and b + a both work):

An explicit constructor:

A copy constructor must receive its argument by reference because:

Which of the following operators cannot be overloaded?

To prevent class objects from being copied:

Which statement is false?

Conversion constructors:

A copy constructor:

Which of the following is false?

Which of the following statements about a unique_ptr object is true?

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 of the following is false about the new operator and the object for which it allocates memory?
