OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step
Solved in 2 steps
- 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.In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extclockType from the class clockType by adding a member variable to store the time zone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class.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)
- Assume the definition of class houseType as given in Exercise 11. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the member function set so that private members are set according to the parameters. b. Write the definition of the member function print that prints the values of the data members. c. Write the definition of the constructor of the class houseType so that the private member variables are initialized to according to the parameters. d. Write a C++ statement that prints the value of the object newHouse. e. Write a C + + statement that declares an object house of type newHouse, and initializes the member variables of house to "Ranch", 3, 2, 2, 2005, 1300, 185000, and 3600.0, respectively. f. Which function members are accessors and which are mutators?Examine the following classes. The table lists the variables that are members of the Third class (some are inherited). Complete the table by filling in the access specification each member will have in the Third class. Write “inaccessible” if a member is inaccessible to the Third class. class First {private: int a;protected: double b;public: long c;};class Second : protected First {private: int d; protected: double e;public: long f;};class Third : public Second {private: int g;protected: double h;public: long i;}- Access LevelsFill in the blanks in the following table which describes the access levels in a derived class's members.i.e. State whether the member's access level is public, private, or protected - or, if it is not accessible! Class Access specifier Base Class Member Access Level Derived Class Member Access Level public private public protected protected private public protected private private public protected
- In this exercise, you will design a class memberType.a. Each object of memberType can hold the name of a person, member ID, number of books bought, and amount spent.b. Include the member functions to perform the various operations on the objects of memberType—for example, modify, set, and show a person’s name. Similarly, update, modify, and show the number of books bought and the amount spent.c. Add the appropriate constructors.d. Write the definitions of the member functions of memberType.e. Write a program to test various operations of your class memberType10.If all the classes used parameterized constructors and no default constructor then _________ i The object of lower level classes can’t be created ii Object of lower level classes must call parent class constructors explicitly iii Object of lower level classes must define all the default constructors iv Only object of first class can be created, which is first parentUsing C++, write a class named as vehicle which has some attributes this class has three functions.i.e 1 .fuelAmount () 2. loadingCapacity() 3. applyBrakes() 4. enginePower() Write a class named as Bus, Car and Truckwhich are inherited from class Vehicle. Also write the setter/getter, default and parameterized constructor in each class. Write a main which create object of derived class and call all inherited function of base class. Note: Each class should have atleast two attribute of base class
- Question 14 papa .If you want to enable only derived classes to change base class data members, the data members in the base class should be defined as: a. static b. private c. protected d. All of the above Full explain this question and text typing work only We should answer our question within 2 hours takes more time then we will reduce Rating Dont ignore this lineAdhere to the following additional requirements: Each of the 6 classes will have exactly 2 constructors. Every class will have a getSpecies() function. We won't be declaring objects of type "Creature" or "Demon", but you should include getSpecies() functions for them anyway, and they should return "Creature" and "Demon", respectively. Make getSpecies() a public member instead of private. Each of the 5 derived classes will have exactly 4 member functions (including constructors) and no data members The Creature class will have 8 member functions (including 2 constructors, 2 accessors, and 2 mutators) and 2 data members. Do not use the "protected" keyword. Many computer programmers consider it to be poor practice because only the base class itself should have uncontrolled access to that data. The derived classes can access the data members through accessors and mutators. In the non-default constructors for the sub-classes, you will need to use initializer lists. The Creature class's…Q- Answer these questions related to the following code: Name all member functions of all classes visible through temp1 in the main function? Name all member functions of all classes visible through temp2 in the main function? Name all member functions of all classes visible through temp3 in the main function?

Class B { Public: Void b1(); Protected: Void b2(); }; Class A : public B { Public: Void a1(); Protected: Void a2(); }; Class C: public A { Public: Void c1(); }; Void main () { B temp1; A temp2; C temp3; } Subject :…
