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 3 steps
- Design an Account class used to represent an individual’s declining balance gift card. It contains a string for the account number, and a float value for the balance. It should include the following 7 functions: a 2-argument constructor (it accepts an account number and initial balance). a set function, one for each attribute (2 total functions, setAccount and setBalance. Each assigns an argument value to the named member variable. a get function for each attribute (2 total functions, getAccount, and getBalance). Each returns the value stored in the named member variable. a function to display the account’s information to the screen. The account number and balance value should be labelled. a function withdraw that takes a float argument and subtracts it from the balance. Write the class declaration. Member variables should NOT be accessible outside the class! Member functions should be accessible outside the class! Write the member function definitions for only the following…C++ please! Please type it and no pictures. Create a class called Employee that includes three data members: a firstname (type string), a last name (type string), and monthly salary (type int).The class will have a constructor that initializes the three data members.Include the set and get member functions for each data member. If the monthlysalary is not positive, the set function will set it to 0. Also include amember function that returns the yearly salary (i.e. twelve times the monthlysalary).Write a test program that prompts the user to enter the first and lastname of an employee as well as their monthly salary. The program will thenoutput the yearly salary of the employee, give them a 10 percent raise, andoutput the yearly salary again.Use C++ language Create a class called Fraction for performing arithmetic with fractions. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor function that enables an object of this class to be initialized when it is declared. The constructor should contain default values in case no initializers are provided. Provide public member functions for each of the following: a) Addition of two Fraction numbers (included in the Frac.cpp as an example). b) Subtraction of two Fraction numbers. c) Multiplication of two Fraction numbers. d) Division of two Fraction numbers. e) Printing Fraction numbers in the form a/b where a is the numerator and b is the denominator. f) Printing Fraction numbers in double floating-point format.
- C++ language (Composition problem) Given the following two classes A and B, where all member functions have been fully implemented inline. class A { public: void f(int arg) { data = arg; } int g() { return data; } private: int data; }; class B { public: A x; }; int main() { B obj; // ... write code here return 0; } a. Insert the code in the main() function that assigns integer value 99 to the “data” member of obj, which is a B class object). b.Write the code to display the value (i.e., 99) that has just been assigned to the obj. c. Note that only a single object obj of B class is declared. How many times are constructors called? If more than one constructor is called, in what order are they called?Define a Pet class that stores the pet’s name, age, and weight. Add appropriateconstructors, accessor functions, and mutator functions. Also define a functionnamed getLifespan that returns a string with the value “unknown lifespan.” Next, define a Dog class that is derived from Pet. The Dog class should have aprivate member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors.Redefine the getLifespan function to return “Approximately 7 years” if the dog’sweight is over 100 pounds and “Approximately 13 years” if the dog’s weight isunder 100 pounds. Next, define a Rock class that is derived from Pet. Redefine the getLifespanfunction to return “Thousands of years.” Finally, write a test program that creates instances of pet rocks and pet dogs thatexercise the inherited and redefined functions. use c++(C++) 23. True/False: function getGallons() is an inline member function 24. Design a class called Date. The class should store a date in three private integers: month, day, year. There should be a member function to print out the date in the month/day/year format, e.g. 12/25/2015, 4/1/1970 There should be a constructor which takes three parameters to initialize the date. It should not accept values for day greater than 31 or less than 1, or values for month greater than 12 or less than 1. If the constructor is called with these values an error message should be printed out and the field set to 0. Any value for year is acceptable. There do not need to be any other member functions. Provide the class declaration and also the implementation of the member function and constructor.

Subscribe now.arrow_forward Question in c++ Create a class time24, each object is a value represented the time ofday in the form hours, minutes and seconds. Provide a constructorthat enables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in case noinitializes are provided.Provide Public member functions for each of the followingoperations: set the time, print the time, increment the time by onesecond, compare two times for equality, increment the time by onehour, determine if one time is “less than” (comes before) anothertime, and final print the time in format 12 hours.Include any additional operations that you think would be useful foryour class.Design, implement, and test your class.1) Set the complex number according to the parameters such as realPart = real; imaginaryPart = imag Design a constructor no-argument to initialize the complex number Design a constructor to initialize the complex number according to the parameters Overload the operators subtraction and addition this class as member functions. Overload the operator = = to check two complex numbers are the same. Use the friend function for the operators << and >>. For those functions, use the below function definition. 2) 1) Write the definitions of the class complexType. 2) Write a test program that implementing the operators in the class complexType. a) Create a complex number with the real and imaginary part values as 5 and 6, respectively. Let’s assume the object as ‘num1’ in the below output example b) Create a default complex number. c) Design a code to prompt a user for the real and imaginary values from the default object. d) Use the operators +, - and display their results.…C++ Personal Information Class: Design a class that holds the following personal data: name, age, and phone number. Write appropriate accessor and mutator functions. Demonstrate the class by writing a program that creates three instances of it. One instance should hold your information, and the other two should hold your friend's or family member's information.
- In C++ Design a class named QuadraticEquation for a quadratic equation . The class contains: Data fields: a, b, and c that represents three coefficients. A default constructor A constructor for the arguments for a, b, and c. Three get functions for a, b, and c. Three set function for a, b and c. A function named getDiscriminant() that returns the discriminant, which is . Two member functions named getRoot1() and getRoot2() for returning two roots of the equation and These functions are useful only if the discriminant is non-negative. Let these functions return 0 if the discriminant is negative. Implement the class. Write a test program that prompts the user to enter values for , , and , and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display the one root. Otherwise, display “The equation has no roots”.C++ programming 1. Design a class bookType that defines the book as an ADT. Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock. To keep track of the number of authors, add another member variable. Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book. Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock. Add similar operations for the publisher, ISBN, book price, and authors. Add the appropriate constructors and a destructor (if one is needed). Write the…subject: Object oriented programming (OOP): DO TASK IN C++ Define a pure abstract base class called BasicShape . The BasicShape class should have the following members: Private Member Variable: area, type double used to hold the shape's area. Public Member Functions: setArea: assigns received argument to area variable. getArea. This function should return the value in the member variable area. calcArea. This function should be a pure virtual function. Next, define a class named Circle . It should be derived from the BasicShape class. It should have the following members: Private Member Variables: centerX, type integer used to hold the x coordinate of the circle’s center. centerY, type integer used to hold the y coordinate of the circle’s center. radius, type double used to hold the circle's radius.
