Switch, break and default

Create a C# program that calculates a student's grade from an integer. Ask the user for a number (x) and answer the following:

• 10 - A+
• 9 - A
• 7,8 - B
• 6 - C
• 5 - E
• 0,4 - F

Use the switch, break and default instruction of C#.

Input

10

Output

A+

Solution

using System;
public class BreakAndDefault
{
    public static void Main(string[] args)
    {
        int x = Convert.ToInt32(Console.ReadLine());
 
        switch (x)
        {
            case 10:
                Console.WriteLine("A+");
                break;
 
            case 9:
                Console.WriteLine("A+");
                break;
 
            case 8:
            case 7:
                Console.WriteLine("B");
                break;
 
            case 6:
                Console.WriteLine("C");
                break;
 
            case 5:
                Console.WriteLine("E");
                break;
 
            default:
                Console.WriteLine("F");
                break;
        }
    }
}
