TASK 2

1. STUDENT GRADE CALCULATOR
2. Input: Take marks obtained (out of 100) in each subject.
3. Calculate Total Marks: Sum up the marks obtained in all subjects.
4. Calculate Average Percentage: Divide the total marks by the total number of subjects to get the average percentage.
5. Grade Calculation: Assign grades based on the average percentage achieved.
6. Display Results: Show the total marks, average percentage, and the corresponding grade to the user

Code:

import java.util.Scanner;
class StudentGradeCalculator 
{
public static void main(String[] args) 
{
    Scanner inputMarks = new Scanner(System.in);
    System.out.println("Subject 1 (out of 100):");
    float sub1 = inputMarks.nextFloat();
    
    System.out.println("Subject 2 (out of 100):");
    float sub2 = inputMarks.nextFloat();

    System.out.println("Subject 3 (out of 100):");
    float sub3 = inputMarks.nextFloat();

    System.out.println("Subject 4 (out of 100):");
    float sub4 = inputMarks.nextFloat();
    
    float total = sub1+sub2+sub3+sub4;
    float percentage = total/4;
    
    System.out.println("\nTotal Marks = " + total);
    System.out.println("Average Percentage = " + percentage);
   
    if (percentage >= 90 && percentage == 100)
    {
        System.out.println("Grade = A+");
    }
    else if (percentage >= 80)
    {
        System.out.println("Grade = A");
    }
    else if (percentage >= 65)
    {
        System.out.println("Grade = B+");
    }
    else if (percentage >= 55)
    {
        System.out.println("Grade = B");
    }
    else if (percentage >= 30)
    {
        System.out.println("Grade = C");
    }
    else
    {
        System.out.println("Grade = F");
    }

    System.out.println("\n");
    System.out.println("-----------------------------------------------------");
    System.out.println("Grade scale chart : ");
    System.out.println("-----------------------------------------------------");
    System.out.println("90 - 100% = A+ = Very Good");
    System.out.println("80 - 89% = A = Good");
    System.out.println("65 - 79% = B+ = Average");
    System.out.println("55 - 64% = B = Below Average");
    System.out.println("30 - 54% = C = Pass");
    System.out.println("29% and below = F = Fail"); 
}
