{
    class Program
    {
        static void Main(string[] args)
        {
            string result = Console.ReadLine();//键盘接受
            for (int i = 0; i < 4; i++)//允许ABCD都打出来
            {
                switch (result)
                {
                    case "A":
                        Console.WriteLine("A成绩段为80-90");
                        break;
                    //中断最近（本次）循环
                    case "B":
                        Console.WriteLine("B成绩分数段为70-85");
                        break;
                    case "C":
                        Console.WriteLine("C成绩分数段为60-75");
                        break;
                    default://默认
                        Console.WriteLine("60以下");
                        break;

 

                }
                result = Console.ReadLine();
            }

            //Console.Read();
        }
    }
}

//练习二
//学生成绩用ABCE分别显示，使switch条件显示
