- Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.Mark the following statements as true or false. a. In single inheritance, a base class can create only one derived class. (1) b. The public members of a base class can only be inherited as public members in the derived class. (2) c. To redefine (or override) a member function of the base class in the derived class, the corresponding member function must have the same name, number, and type of parameters. (3) d. If the derived class does not override a public member function of the base class, you may specify a call to that public member function by using the name of the function and the appropriate parameter list. (3) e. The constructor of a derived class can specify a call to the constructor of the base class in the heading of the function definition. (4) f. The constructor of a derived class can specify a call to the constructor of the base class using the name of the class. (4) g. Suppose that x and y are classes, one of the member variables 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. (4) h. When the destructor of the derived class executes, it automatically invokes the destructor of the base class. (5) i. The class ios is the base class for all stream classes. (7) j. In protected inheritance, the private members of the base class are protected members of the derived class. (8) k. In composition, one or more members of a class are objects of another class type. (9)What is the difference between a friend function of a class and a member function of a class? (3)
- Programming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…Polymorphism : Write a driver program that uses a AECar reference variable to point to three different types of classes, showing that inheritance is one mechanism for using polymorphism.С++ Multiple inheritance is When a class is derived from another class When a class is derived from other two derived classes When a class is derived from two or more classes When a class is derived from exactly one class
- True or False Polymorphism allows a class variable of the base class type to reference objects of either the base class or the derived class types.Search courses Midterm Exam Spring21 All the following is true about private inheritance except Select one O A derived class member functions have access to all protected members inherited from the base clasS O A derived class objects does not have access to public members inherited from the base class A derived class inherits all base class methods including.constructors, destructors and copy constructor of the base class. O The constructor of a derived class can trigger a call to the constructor of the base class in the headinge the function definition, O Adenved class objects does not have access to the private and protected members inhented from the base class, OAll the statements are true GETrue or False ___(34) The has-a relation between two classes (such as class A has class B) leads to inheritance where class B can inherit properties from class A. ___(35) When a user adds a user-defined constructor a class, the default constructor is no longer available unless it is explicitly defined again in the class. ___(36) If class B is a child class of class A, when you create an object from class B, only the constructor of class B is used to create the object.
- If a class is derived privately from the parent class then . Select one: a.the compiler gives an error b.all the members are inherited by the child class but are inaccessible c.no members of the base class is inherited d.all members are accessible by the child classA constructor has the same name as the class and is automatically called when a new object of the class is created. It is used to perform initialization functions. A constructor may or may not have input arguments. The keyword extends is used to indicate inheritance. Class B extends Class A implies that Class B is inheriting the attributes and methods of class A. Class A is the base class and Class B is the derived class. It is also possible for the derived class to reference the constructor of the base class in its constructor. This will avoid duplicating initialization functions. note:write the java code and don't use any packageThe module view of inheritance refers to: Dynamic binding Every operation applicable to the instances of a superclass is also applicable to the instances of its subclasses. A subclass describes an extension of the parent module O A subclass describes a subtype of the parent type Which statement about encapsulation is incorrect. Encapsulation provides a way to cope with change Encapsulation conceptualizes a problem at a higher level of abstraction Encapsulation facilitates software maintenance O Encapsulation conceptualizes a problem at a lower level with specific data structures O O
