Letter Grade Calculator & Flow Chart

Problem:

You have been asked to write a program to calculate the final numerical average and alphabetical grade based on three test scores. The program should allow the user to input the scores of three tests. The program should output the student’s name, numeric average and final letter grade based on the following grading scheme.

A= 90-100 B= 80 – 89 C= 70 – 79 D= 60 – 69 F= 59 <=

Steps:

1. Create a Flow Chart demonstrating what decisions must be made.
2. Design a program to calculate the numerical and apathetical scores.
3. Test your program with the following data:

Student: SJohnson Test1 95 Test2 88 Test 3 73

/** * This program will calculate the average score of three test for a specific student. * The output will be in both numerical and alphabetical form. * * @author Jeannie Ray) * @version (10/02/06) */

import java.util.Scanner;

public class GradeCalculator
{
public static void main (String[] args) { // instance variables - int test1 = 0; int test2 = 0; int test3 = 0; int avgTest = 0;

Scanner in = new Scanner (System.in);

//allow for user name input System.out.print ("What is your name? "); String input = in.next();

//allow user to input test scores System.out.print ("What is your score on the first test? "); test1 = in.nextInt(); System.out.println("Thank you!"); System.out.println();

System.out.print ("What is your score on the second test? "); test2 = in.nextInt(); System.out.println ("Thank you!"); System.out.println();

System.out.print ("What is your score on the third test?"); test3 = in.nextInt(); System.out.println ("Thank you!"); System.out.println();

//calculate the average score from all three tests avgTest = (test1 + test2 + test3)/3;

if (AvgTest>89) System.out.println (input + " your numerical average equals " + avgTest + " which is equivalent to an 'A'!"); else if (avgTest>79 && avgTest<90) System.out.println(input + " your numerical average equals " + avgTest + " which is equivalent to a 'B'!"); else if (avgTest>69 && avgTest<80) System.out.println(input + " your numerical average equals " + avgTest + " which is equivalent to a 'C'!"); else if (avgTest>59 && avgTest<70) System.out.println(input + " your numerical average equals " + avgTest + " which is equivalent to a 'D'!"); else System.out.println(input + " your numerical average equals " + avgTest + " which is equivalent to a 'F'!");
