Implement the GradedActivity class. Copying from the pdfs is fine.

Create a new class Assignment which is derived from GradedActivity. It should have three private member ints for 3 different parts of an assignment score:
functionality
(max 50 points),
efficiency
(max 25 points), and
style
(max 25 points).

Create member function set() in Assignment which takes three parameter ints and sets the member variables. It should also set its score member, which is inherited from GradedActivity, using the setScore() function, to functionality + efficiency + style. Signature:

void Assignment::set(int, int, int)

Create a main program which instantiates an Assignment, asks the user for its functionality, efficiency, and style scores, and prints out the score and letter grade for the assignment.

Examples from the pdfs:

d PassFailExam::set(int q, int m, int p) { double numericScore, pointsEach;

numQuestions = q;
numMissed = m;
numToPass = p;
pointsEach = 100.0 / numQuestions;
numericScore = 100.0 - (numMissed * pointsEach);

setScore(numericScore); char PassFailExam::getLetterGrade() const {

if ((numQuestions - numMissed) >= numToPass) return 'P';

else return 'F';

}

___________________________________________________

class PassFailExam : public GradedActivit { private: int numQuestions; int numMissed; int numToPass; public: PassFailExam()

{ numQuestions = 0; numMissed = 0; numToPass = 0; }

void set(int, int, int); char getLetterGrade() const;

};

___________________________________________________

class GradedActivity { protected: double score; public: GradedActivity()

{ score = 0.0; } GradedActivity(double s)

{ score = s; }
void setScore(double s)

{ score = s; } double getScore()

{ return score; } char getLetterGrade() const;

};

___________________________________________________

PassFailExam quiz;

quiz.set(10,2,8);
cout < "the="" score="" on="" quiz="" is:="">
cout < quiz.getscore()=""><>
cout < "the="" letter="" grade="" is:="">
cout < quiz.getlettergrade()=""><>
