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:

- Write a class Teacher that contains the attribute teacher name, age and address. It alsocontains member function to input and display its attributes. Write another class Author Writeanother class Writer that contains the attributes writer name, address and number of books writtenby him. It also contains member functions to input and display its attributes. Write a third classScholar that inherits both Teacher and Writer classes. Note: Solve this using c++Redo Programming Exercise 3 by overloading the operators as nonmembers of the class boxType. Write a test program that tests various operations on the class boxType. Reference: Chapter 11 defined the class boxType by extending the definition of the class rectangleType. In this exercise, derive the class boxType from the class rectangleType, defined in Exercise 1, add the functions to overload the operators +,–, *, ==, !=, <=, <, >=, >, and pre- and post-increment and decrement operators as members of the class boxType. Also overload the operators << and >>. Overload the relational operators by considering the volume of the boxes. For example, two boxes are the same if they have the same volume. Write the definitions of the functions of the class boxType as defined above and then write a test program that tests various operations on the class.Consider the definition of the class product Type as given in Exercise 8. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the function set so that instance variables are set according to the paramaters. Instance variables quantitieslnStock, price, and discount must be nonnegative. b. Write the definition of the function print to output the values of the instance variables. c Write the definition of the function setQuantitiesInStock to set the value of the instance variable quantitiesInStock according to the parameter. d. Write the definition of the function updateQuantitiesInStock to update the value of instance variable quantitiesInStock by adding the value of the parameter. e. Write the definition of the function getQuantitiesInStock to return the value of instance variable quantitiesInStock. f. Write the definition of the function setPrice to set the value of the instance variable price according to the parameter. g. Write the definition of the function getPrice to return the value of the instance variable price. h. Write the definition of the function setDiscount to set the value of the instance variable discount according to the parameter. i. Write the definition of the function getDiscount to return the value of the instance variable discount.
- 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.Consider the definition of the class product Type as given in Exercise 8. Which function members are accessors and which are mutators? (4)Consider the definition of the following class: (1, 2, 3, 5, 7) a. Give the line number containing the constructor that is executed in each of the following declarations. b. Write the definition of the constructor in Line 4 so that the instance variables are initialized to " ", " ", " ", 0, 0.0, and 0.0, respectively. c Write the definition of the constructor in Line 5 so that the string instance variables are initialized to"", and the other instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. d. Write the definition of the constructor in Line 6 so that the instance variables productName and manufacturer are initialized to the empty string, instance variable id is initialized according to the first parameter, and the remaining instance variables are initialized according to the last three parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative. e. Write the definition of the constructor in Line 7 so that the instance variables are initialized according to the parameters. Instance variables quantitieslnStock, price, and discount must be nonnegative.
- 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?Define a default constructor that initializes the data members, string title and integer year, with the default values "Empty" and -1, respectively. Ex: If the input is Magnolia 1989, then the output is: Title: Empty, Year: -1 Title: Magnolia, Year: 1989 Note: The class's print function is called first after the default constructor, then again after the inputs are passed to the setters. 1 #include 2 #include 3 using namespace std; 4 5 6 7 8 9 10 11 12 13 14 class Book { public: Book(); void SetTitle(string book Title); void Set Year (int bookYear); void Print (); private: string title; int year; CSScanne 17 Your code goes here */ 18 amScannerA C++ assignment Implement the GradedActivity class. Copying from the pdfs is fine. Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score: functionality (max 50 points), efficiency (max 25 points), and style (max 25 points). Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style.
