Add an if-else statement displaying a message indicating whether or not the exam was passed. Assume that 60% is the minimum passing grade.

// This program determines the percentage grade on

// an exam, given the number of questions missed,

// how many points each question was worth,

// and the total points possible.



#include 

using namespace std;

int		pointsPerQuestion;

double	percentageGrade;

cout << "Enter the total points possible on the exam => ";

cin  >> pointsPossible;

cout << endl;

cout << "Enter the number of points per question => ";

cin  >> pointsPerQuestion;

cout << endl 

cout <<"Enter the number of questions missed => ";

cin >> numberMissed;



percentageGrade = pointsPossible - numberMissed * pointsPerQuestion  /   					pointsPossible  *  100;



cout << endl << "The percentage grade is ";
