- Write in C++ Language (Happy Coding):Create a class named 'Programming'. While creating an object of the class, if nothing is passed to it, then the message "I love programming languages" should be printed. If some String is passed to it, then in place of "programming languages" the name of that String variable should be printed.For example, while creating the object if we pass "cpp", then "I love cpp" should be printed.Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…Create a class “Student” with data members such as roll number, name and branch.

- INSTRUCTIONS: Write a C++ script/code to do the given problem. Write a class called profileID, which has data members firstName,lastName, age, birthday and ageCompany (the age when you entered in the company). Remember to use set and get methods to access the data members this time. Also, write another class called bonusAward that has a method getBonus()with arguments yos and etype which are both integer data types. This method calculates the bonus received by an employee using this formula: yos*1000 + etype*1000. Write two derived classes, ASE and SE, using multiple inheritance usingprofileID and bonusAward as parent classes. Both classes must have amethod named getyos()that returns the yos of an employee using the formula age–ageCompany; and a method named getetype() which returns a constant based on the employee type. For ASE, the constant is 10 while for SE that constant is 20. Last, write a main program where you instantiate ASE as employee1 and SE as employee2. Get their…This would be for C++ Write a program that calculates a target heart rate. It should have a class called Heart that has a string name and an int age. This class should have getter and setter methods for those member variables. It should also have a method that returns the maximum heart rate which is 220 minus age, a method that returns the maximum target heart rate which is 85% of the maximum heart rate, and a method that returns the minimum target heart rate which is 50% of the maximum. Write a driver program that prompts the user for a name (use getline to get names with spaces) and age and then prints the name, age, maximum heart rate, and the target heart rate. The output needs to be able to recreate the example shown below. Here is an example run of the program would be the following as the assignment shows Please tell me your name: Jake Peralta Please tell me your age: 37 Your name is Jake Peralta Your age is 37 Your maximum heart rate is 183 Your target heart rate is 91-155Create a class “Student” with data members such as roll number, name and branch.

- Create a simple C++ program with the 3 following classes. Use separate header and source files for each class. Make all of the class members public. Player name char[32] x, y floats sword - Sword * hit points - int max points - int Player() default constructor Player(char *) - constructor that sets the name heal (Flask *) - heals the player if their health is low and the flask passed in has charges. Do not over heal the player. display() prints the name, sword name and current hit points of the player. Sword name char[32] damage - int attack speed - float Sword() default Sword (char *) set the name Flask name char[32] charges (remaining) int health restored per charge - int Flask() In main create an instance of the Player class and 3 objects from the Sword class. All of these objects must be created on the heap by using the new keyword. Give the swords different names, damage and attack speed values. Equip the player with one of the swords by assigning one of the Sword objects to the…write the code in c# Create a class with name savingaccont.In this class you have to write the static method having name CalculteFutureValue which takes three parameters of type double along with return type double.This function should implement the formula given below.The formula, which is known as the future value formula, is:F = P * (1 + i)tThe terms in the formula are as follows: F is the future value of the account after the specified time period. P is the present value of the account. i is the monthly interest rate . t is the number of months . Write Driver class which contains main function that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named CalculteFutureValue that returns the future value of the account, after the specified number of months. The program should display the account’s future value.1. Develop a C++ class called PrimeNumberGenerator. An object of this class will generate successive prime numbers on request. Think of the object as being similar to the digital tasbeeh counter. It has a reset button which makes the counter retum to 0. There is also a button to get the next prime number. On the tasbeeh, pressing this button increments the current value of the counter. In your object, pressing this button would generate the next prime number for display. You'll implement the reset button as a member fumction reseto and the other button as a function getNextPrime). When an object is first created and the getNextRrime) function is called, it will retum the first prime number, i.e., 2. Upon subsequent calls to the getNextPrime0 function, the subsequent prime numbers will be retumed. Define any others functions such as constructor and attributes that you need. According to Wikipedia: "a prime number is a natural number greater than 1, that has no positive divisors other…
- Please include doctring, and write only in python: First, write a class named Movie that has four data members: title, genre, director, and year. It should have: an init method that takes as arguments the title, genre, director, and year (in that order) and assigns them to the data members. The year is an integer and the others are strings. get methods for each of the data members (get_title, get_genre, get_director, and get_year). Next write a class named StreamingService that has two data members: name and catalog. the catalog is a dictionary of Movies, with the titles as the keys and the Movie objects as the corresponding values (you can assume there aren't any Movies with the same title). The StreamingService class should have: an init method that takes the name as an argument, and assigns it to the name data member. The catalog data member should be initialized to an empty dictionary. get methods for each of the data members (get_name and get_catalog). a method named add_movie…!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilıHello please solve the below in C++. I used the code provide by a Bartleby expert and I was marked down, the feedback was “it doesn't overload the operators as it should” Question Create a class called Rational (separate the files as shown in the chapter) for performing arithmetic with fractions. Write a program to test your class. Use integer variables to represent the private data of the class-the numerator and the denominator. Provide a constructor that enables an object of this class to be initialized when it's declared. The constructor should contain default values in case no initializers are provided and should store the fraction in reduced form. For example, the fraction 2/4 would be stored in the object as 1 in the numerator and 2 in the denominator. Provide public member functions that perform each of the following tasks: Make an overloaded operator of the + symbol for the add method - Adds two Rational numbers. The result should be stored in reduced form. Make an overloaded…
