Design an Essay class that is derived from the GradedActivity class: class GradedActivity{ private: double score; public: GradedActivity() {score = 0.0;} GradedActivity(double s) {score = s;} void setScore(double s) {score = s;} double getScore() const {return score;} char getLetterGrade() const; }; char GradedActivity::getLetterGrade() const{ char letterGrade; if (score > 89) { letterGrade = 'A'; } else if (score > 79) { letterGrade = 'B'; } else if (score > 69) { letterGrade = 'C'; } else if (score > 59) { letterGrade = 'D'; } else { letterGrade = 'F'; } return letterGrade; } The Essay class should determine the grade a student receives on an essay. The student's essay score can be up to 100, and is made up of four parts: Grammar: up to 30 points Spelling: up to 20 points Correct length: up to 20 points Content: up to 30 points The Essay class should have a double member variable for each of these sections, as well as a mutator that sets the values of these variables. It should add all of these values to get the student's total score on an Essay. Demonstrate your class in a program that prompts the user to input points received for grammar, spelling, length, and content, and then prints the numeric and letter grade received by the student. I just need the numeric grade my code: #include using namespace std; class GradedActivity { private: double score; public: GradedActivity() { score = 0.0; } GradedActivity(double s) { score = s; } void setScore(double s) { score = s; } double getScore() const { return score; } char getLetterGrade() const; }; char GradedActivity::getLetterGrade() const { char letterGrade; if (score > 89) { letterGrade = 'A'; } else if (score > 79) { letterGrade = 'B'; } else if (score > 69) { letterGrade = 'C'; } else if (score > 59) { letterGrade = 'D'; } else { letterGrade = 'F'; } return letterGrade; } class Essay :public GradedActivity { private: //scores for various sections double grammar_Score,spelling_Score,length_Score,content_Score; public: double getgrammar_Score()const { return grammar_Score; } void setgrammar_Score(double s) { grammar_Score = s; } double getspelling_Score()const { return spelling_Score; } void setspelling_Score(double s) { spelling_Score = s; } double getlength_Score()const { return length_Score; } void setlength_Score(double s) { length_Score = s; } double getcontent_Score()const { return content_Score; } void setcontent_Score(double s) { content_Score = s; } char getGrade() { double score = grammar_Score + spelling_Score + length_Score + content_Score; setScore(score); char grade = getLetterGrade(); return grade; } }; int main() { Essay essay; double grammar_Score,spelling_Score,length_Score,content_Score; cout<<"Enter points received for grammar:"; cin>>grammar_Score; essay.setgrammar_Score(grammar_Score); cout<<"Enter points received for spelling:"; cin>>spelling_Score; essay.setspelling_Score(spelling_Score); cout<<"Enter points received for correct length:"; cin>>length_Score; essay.setlength_Score(length_Score); cout<<"Enter points received for content:"; cin>>content_Score; essay.setcontent_Score(content_Score); cout<<"Numeric Grade: " <

The Essay class should determine the grade a student receives on an essay. The student's essay score can be up to 100, and is made up of four parts:
- Grammar: up to 30 points
- Spelling: up to 20 points
- Correct length: up to 20 points
- Content: up to 30 points
The Essay class should have a double member variable for each of these sections, as well as a mutator that sets the values of these variables. It should add all of these values to get the student's total score on an Essay.
