Solved in 2 steps
- A c++ a program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Note: Solve as soon as possible use OOP Concepts1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
- What statements about the destructor of an object are accurate? a. The destructor of a class is a member function that is automatically activated when an object becomes inaccessible. b. The destructor has no arguments and its name must be the character ~ followed by the class name (e.g., ~bag for the bag class). c. Because the destructor is automatically called, programs rarely make explicit calls to the destructor, and we generally omit the destructor from the documentation that tells how to use the class. d. The primary responsibility of the destructor is simply releasing dynamic memory. c & d a, b, & c b & c a & b a, b, c, & dHow many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than threeCreate a base class with two methods. In the first method, call thesecond method. Inherit a class and override the second method.Create an object of the derived class, upcast it to the base type, andcall the first method. Explain what happens.
- __________ is the default behavior when an object is assigned the value of another object of the same class.Public members of a base class can be accessed by anything from outside the base class. Private members can be accessed only by the base class and derived classes. Protected members can be accessed by the base class and any of its descendants (child class or child of a child class). answer choices True FalseCreate a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
- .If all the classes used parameterized constructors and no default constructor then _________i The object of lower level classes can’t be createdii Object of lower level classes must call parent class constructors explicitlyiii Object of lower level classes must define all the default constructorsiv Only object of first class can be created, which is first parentYou cannot use the isinstance function to determine whether an object is an instance of a subclass of a class.True or FalseExamine the following code and select the correct statements (choose all possibleoptions): class Bottle {Bottle() {}Bottle(WaterBottle w) {}}class WaterBottle extends Bottle {WaterBottle() { }WaterBottle(Bottle w) { } } a) The class Bottle defines two overloaded constructors.b) The class WaterBottle defines two overloaded constructors.c) The class compiles successfully—a base class can use reference variables of its derived class as method parameters.d) Bottle and WaterBottle cause syntax errors.e) The class compiles successfully - A derived class can use reference variables of its base class as method parameters.f) A base class can’t pass reference variables of its defined class, as method parameters in constructors.
