Write a class named Grade that has the following member variables and functions. Variables : protected: double score, char letter Functions: Required Constructors Getscore() // it will return score Getgrade() // it will assign the grades to letter variable and returns it.

Question1: first, define the rectangle class which has two functions for calculating area and perimeter. then write a c++ program that in its main function has 2 square objects and calculate their area and perimeter. for each object ask the user to give you the sides.

Need correct program in C++ Create a class that imitates part of the functionality of the basic data type int. Call the class Int (note different capitalization). The only data in this class is an int variable. Include member functions to initialize an Int to 0, to initialize it to an int value, to display it (it looks just like an int), and add two Int values. Write a program that exercises this class by creating one uninitialized and two initialized Int values, adding the two initialized values and placing the response in the uninitialized value, and then displaying this result.

1. Define a new C++class named “PurchaseOrder” that manages a purchase: number of items(integer), cost per item(double), and the description of the purchase(string). Please note that the total can be derived from multiplying the quantity with the cost per item and should not be a data member. The class must provide at least the following two methods: •toString methods that return the string containing all the information about the purchase order in the following format: Description(<purchase-descripton>) Quantity(<number-of-items) Cost(<cost-per-item>) Total(<total-cost-of-this-purchase>) For example, here is a specific purchase order: Description(A box of candy) Quantity(100) CostPerItem($1.25) Total($125.00) •compareTotal method that compares the information between the 2 PurchaseOrderobjects and returns -1 if the total of the first purchase is less, 0 if they both have the same total, and 1 if greater. Please make use of the fact that there must be an object to…

Hello, I am having trouble with this homework question for my c++ course. Implement a Rational Number class with the following specifications. Data members a) numerator and denominator Functions a) Constructors: 1) default constructor 2) single parameter constructor to create numerator/1 3) dual parameter constructor to create numerator/denominator 4) Use constructor delegation across all constructors. b) Accessors and Mutators for both data members. c) Static recursive GCD function using Euclid's algorithm. d) Static LCM function for two numbers. e) Reduce function simplify a rational number. This function modifies its calling object. f) Your program should work with the supplied driver program. Notes LCM (Least Common Multiple) This function returns the smallest multiple of a and b. Step 1: Multiply a and b to find a common multiple. Step 2: Divide the common multiple by the GCD of a and b. Step 3: Return the result of Step 2. Reduce: This function reduces a fraction to…

C++ coding project just need some help getting the code thank you!
1-Write a C++ class and name it Base. The Base class has two constant private fields: one of type string called name and one of type integer called age; and a constructor that accepts two inputs The Base class also has three public methods: get_name() that returns the name field, get_age() that returns the age field, and get_info() that returns the following string (The name is name at the age of age.) 2-Write another C++ class and name it Derived. The Derived class inherits form the base class. The Derived class has one private field, type, of type string, a public method, get_type(), which returns the type, and a constructor that accepts three inputs. The Derived class also has another public method that overrides the get_info() method, inherited from the Base class, which returns the following string (The name is name (type) at the age of age.) 3-Write a C++ program and create an instance of the Base and Derived class. Call all the method of the two classes (3 methods for the first…
