4. Define an accessor method (also known as getter) and a mutator method (also known as setter)for each attribute of the class. For example, as for the attribute code, define two methods for it,i.e., getCode () and setCode (). Keep in mind that the accessors should be declared asconstant methods.5. Define three more accessor methods below:a. a method that determines the grade earned for the subject based on the score. For example,if the score earned is 70, this method should return "B+".b. a method that determines the point value of the grade earned. For example, if the gradeearned is "B+", this method should return 3.33.c. a method that determines the point earned for the subject. For example, if the subject is 3credit hour and the grade point earned is 3.33, this method should return 9.99See the section below for the formulas.6. In the main function, write the code to accomplish the following requirements:a. Instantiate or create an object from the class.b. Read inputs from the user and use them to set the attributes of the object.c. Print the subject information such as the code, name, score, grade, etc. See example runsin the following figures for the expected results. In this exercise, you will be writing a C++ program that displays the grade earned for given score of asubject. You will be using an Object-Oriented Programming (OOP) approach to write the program.Notes:Write the program in a single source code file and use the inline style to define the class. Thatmeans, the definition of each method is written directly in the class declaration.• Follow proper naming convention:o Use camel Case to name functions, methods, and variables.▪ Example: int calculateTotal(), int thisIsVariableOUse Pascal Case to name class and data type.Example: class Student { }o Use CAPITAL case to all characters to name constants.▪ Example: const int MAXIMUM_STUDENT = 10;o Use small case to all characters to name a file■ Example:my_main_program.cppModify the starter program provided (main.cpp) to accomplish the following tasks:1. Declare a class to model subject information which consists of three attributes, the subject's name,code, and the score earned for the subject. In your code, you should also implement the "datahiding" principle for the class.2. Define two constructors for the class as follows:a. a parameterized constructor which accepts parameters to set the attributes.b. a default constructor method which sets the attributes to "empty" values3. Define the destructor method for the class which does nothing.
