Grade Ranking with if Statements

In this problem, you will create a program that reads a test score from standard input, determines a grade rank (A/B/C/D) using chained if-else if-else statements, and displays the result to standard output.

Learning Objective: Understand chained if-else if-else for range-based conditions

Overview

3. Read the score with Scanner and print Score: <score> -> Grade: <grade>

Input

<score>

One integer line (0–100)
