The constructor of a derived class specifies a call to the constructor of the base class using the name of the class. c. Suppose that x and y are classes, one of the data members of x is an object of type y, and both classes have constructors. The constructor of x specifies a call to the constructor of y by using the object name of type y. d. A derived class must have a constructor. e. In C++, all operators can be overloaded for user-defined data types. f. In C++, operators cannot be redefined for built-in types. g. The function that overloads an operator is called the operator function. h. C++ allows users to create their own operators. i. The precedence of an operator cannot be changed, but its associativity can be changed. j. Every instance of an overloaded function has the same number of parameters. k. It is not necessary to overload relational operators for classes that have only int data members. l. The member function of a class template is a function template. m. When writing the definition of a friend function, the keyword friend must appear in the function heading. n. The function heading of the operator function to overload the preincrement operator (++) and the postincrement operator (++) is the same because both operators have the same symbols.
