Question

33. Some schools have a grade-replacement policy: A student can retake a course, remove the old grade, and post the new grade in the record. Using the implementation of the gradeRecord class from Programming Exercise 1-32, create a new header file "xgrade.h" that adds the member function replaceGrade) to the gradeRecord class. void replaceGrade(int oldUnits, int oldGradePts int newUnits, int newGradePts); The function updates the grade record by first deleting the old units and grade points and then adding the new grade information. Write a program that declares the grade Record object dHarris. After initially displaying the GPA, indicate the effect of replacing four units of D (one gradept per unit) with anA

Explanation / Answer

Please find the code belo :

void gradeRecord::replaceGrade(int oldUnits, int oldGradePts, int newUnits, int newGradePts)

{

units = units - oldUnits + newUnits;

gradepts = gradepts - oldGradePts + newGradePts;

}

int main()

{

gradeRecord dHarris("558-25-4424",100,180);

cout<<"GPA : "<<dHarris.gpa();

dHarris.replaceGrade(4,4,4,16);

cout<<"Revised GPA : "<<dHarris.gpa();

return 0;

}

Please merge above code to your existing code to get output.
