help me to write programm that use class inherits Polymorphism, and Virtual Functions from

Design a ProgrammingProject class that is derived from the GradedActivity class presented in your book. The ProgrammingProject class should determine the grade a student receives on a programming project. The student's total scores can be up to 100, and is determined in the following manner:

Use of classes: 15 points

Code Execution: 35 points

Proper Choice of Code: 21 points

Correct Pseudocode: 10 points

Use of comments: 11 points

Input/Output/professionalism: 8 points

Your ProgrammingProject class should define these point categories as member variables. After entering the scores, a total should be returned, as well as the letter grade, which is obtained from the parent class, GradedActivity.

Make sure that your member data is protected (with low level validation that creates an Exit_Failure when necessary). Validate user's input (high level validation) for all scores >=0 so that your program doesn't cause an Exit_Failure down in the object.

Create a user-interface program to demonstrate your class. Make your input and output professional. Break your code down into functions as necessary.

Programming Notes:

The ProgrammingProject class is based on (inherits from) the GradedActivity.

The ProgrammingProject class will contain members for the scores and the associated mutator/accessor functions, BUT it will call the setScore function and the getLetterGrade function from GradedActivity.

The main program will prompt and input and do high-level validation and store the results and then create the output display.

This isn't a particularly taxing assignment, so spend some time really doing nice work. Show me how you can shine!

Submit to me: main .cpp and .h and all files

I need something like that one this example of :

Contents of GradedActivity.h (Version 3) 1 #ifndef GRADEDACTIVITY_H 2 #define GRADEDACTIVITY_H 3 4 // GradedActivity class declaration 5 6 class GradedActivity 7 { 8 protected: 9 double score; // To hold the numeric score 10 public: 11 // Default constructor 12 GradedActivity() 13 { score = 0.0; } 14 15 // Constructor 16 GradedActivity(double s) 17 { score = s; } 18 19 // Mutator function 20 void setScore(double s) 21 { score = s; } 22 23 // Accessor functions 24 double getScore() const 25 { return score; } 26 27 virtual char getLetterGrade() const; 28 }; 29 #endif
