import java.util.Scanner;

public class GradeCalculator {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);

        // Prompt the user to enter a score
        System.out.print("Enter the score: ");
        int score = scanner.nextInt();

            grade = "B";
        } else if (score >= 70 && score < 80) {
            grade = "C";
        } else if (score >= 60 && score < 70) {
            grade = "D";
