            string str_name = Console.ReadLine();

            Console.WriteLine("请输入你的英语成绩：");
            string str_english = Console.ReadLine();
            int chinese = Convert.ToInt32(str_chinese);
            int math = Convert.ToInt32(str_math);
            int english = Convert.ToInt32(str_english);
            int sum = chinese + english + math;
            int avg = sum / 3;
            Console.WriteLine(str_name);
            Console.WriteLine("你的总成绩：{0}，平均成绩：{1}", sum, avg);
            Console.ReadKey();

2、#让用户输入天数，并计算这个天数是几周零几天
程序

 Console.WriteLine("请输入天数：");
