this is my .cpp file
#include "GradedActivity. h"
//
// Member function GradedActivity::getLetterGrade *
//
char GradedActivity::getLetterGrade() const
{
char letterGrade; // To hold the letter grade
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;
}
this is the .H file
#ifndef GRADEDACTIVITY_H
#define GRADEDACTIVITY_H
// GradedActivity class declaration
class GradedActivity
{
protected:
double score; // To hold the numeric score
public:
// Default constructor
GradedActivity()
{ score = 0.0; }
// Constructor
GradedActivity(double s)
{ score = s; }
// Mutator function
void setScore(double s)
{ score = s; }
// Accessor functions
virtual double getScore() const
{ return score; }
virtual char getLetterGrade() const;
};
