Grade

by: bs0d

Description:

Visual C++ source code that uses if and else if's to calculate a students grade based on test scores entered.

Code:

//Displays a student's grade

#include <iostream>
using namespace std;

//function prototypes
int getPointsEarned();
char assignGrade(int);

int main()
{
	//declare variables
	int totalEarned = 0;
	char grade      = ' ';
	
	//get total points earned
	totalEarned = getPointsEarned();
	//assign grade
	grade = assignGrade(totalEarned);
	//display grade
	cout << "Grade: " << grade << endl;
	
	return 0;
}   //end of main function

//*****program-defined functions*****

int getPointsEarned()
{
	//get and accumulate the score, then return the total
	int score = 0;
	int total = 0;

cout << "Enter the first score: ";
	cin >> score;
	while ( score >= 0)
	{
		total = total + score;
		cout << "Enter the next score: ";
		cin >> score;
	} // end while loop.
	return total;
} //end of getPointsEarned function.

char assignGrade(int points)
{
	//assigns the letter grade
	char letterGrade = ' ';

if (points >= 360)
		letterGrade = 'A';
	else if (points >= 320)
		letterGrade = 'B';
	else if (points >= 280)
		letterGrade = 'C';
	else if (points >= 240)
		letterGrade = 'D';
	else letterGrade = 'F';
	//end ifs 
	return letterGrade;
}	//end of assignGrade function
