using System;

class HelloWorld {

static void Main() {

Console.WriteLine("Please input a letter grade:");

//get grade from the user

char grade=Console.ReadLine()[0];

//switch block

switch(grade) {

//check if grade is A

//if A then print 4

case 'A': Console.WriteLine("GPA point: 4");

break;

case 'B': Console.WriteLine("GPA point: 3");

break;

//check if grade C then print 2

case 'C': Console.WriteLine("GPA point: 2");

break;

case 'D': Console. WriteLine("GPA point: 1");

break;

case 'F': Console.WriteLine("GPA point: 0");

break;

//if any other letter other then a,b,c,d,f
