Assume that a class called Number, with private member n that is an integer, has already been declared. Please write the definition for the overloaded operator ++, used for preincrement. Code your function as if defined in Number.cpp (i.e. outside of the class declaration). That means use the class name and the scop resolution operator in your header.

- Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the resultProblem: Create a Fraction class with two private positive integer member variables numerator and denominator, one constructor with two integer parameters num and den with default values 0 and 1, one display function that print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4 should be displayed as ½.Assume that a class called Number, with private member n that is an integer, has already been declared.

- In C++, Create a class called Date that includes three data members: amonth(type int), a day(type int), and a year(type int). The Date class willhave a constructor with three parameters to initialize the three data members.You may assume the values provided for the year and day are correct, but makesure that the month value is in the range 1-12; if it isn't, set the month to1. Provide set and get functions for each data member. Provide a memberfunction displayDate that displays the date in format MM/DD/YYYY.Write a test program that prompts the user to input the month, the day,and the year and uses your Date class to output the formatted date.Create a class called Employee that includes three pieces of information as data members—a first name (type string), a last name (type string) and a monthly salary (type int). Your class should have a constructor that initializes the three data members. Provide a set and a get function for each data member. If the monthly salary is not positive, set it to 0. Write a test program that demonstrates class Employee’s capabilities. Create two Employee objects and display each object’s yearly salary. Then give each Employee a 10 percent raise and display each Employee’s yearly salary again.IN C++, create a class called Employee that includes three pieces of information as data members—a first name (type string), a last name (type string) and a monthly salary (type int).

- The operator that is required to access members of classes and structs is called: a. Colon operator b. Scope resolution operator c. Operator overloading d. Member access operator e. None of the answers Answer: What is the name of the program that uses and interacts with the class? Answer: By assuming that all libraries are included, replace MYFUNCTION with the proper function name to make the code correct: 001010 111101101 01010101111110 1010101010101 111010101010 0101100 vector> MyVector; int rows= 10, cols = 4; MyVector.MYFUNCTION(rows, vector(cols, 100)); cout << MyVector [0] [1] << endl; for (int i } = 0; i < MyVector.size(); i++) { for (int j 0; j < MyVector[i].size(); j++) cout << MyVector[i][j] << " "; cout << endl;Suppose you are writing a class called Student that has two private members, std::string name and int perm. Write the function prototype (function declaration) only for a default constructor for Student. For full credit, include the semicolon that terminates the prototype, but do not write the body of the constructorCreate a class called Name that contains data members of type string called first name, middle name, last name, and salutation. Add a constructor that takes four parameters which are used to initialize the four data members and a member function called to-string that returns the person's full name in the form of “Salutation First name Middle name Last name”. Finally add set and get functions for all the data members. Add a destructor to the program displaying a suitable msg.
- 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.C++ OOP use classes only..Create a class called Rational 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. Provide public member functions that perform each of the following tasks: Adding two Rational numbers. The result should be stored in reduced Subtracting two Rational numbers. The result should be stored in reduced Multiplying two Rational numbers. The result should be stored in reduced Dividing two Rational numbers. The result should be stored in reduced Printing Rational numbers in the form a/b, where a is the numerator and b is the denominator. Printing Rational numbers in floating-pointformat
