函数的基本使用

比赛打分      

  static void Main(string[] args)
        {
            int[] a = new int[6];
            int max = 0, min = 1000, sum = 0;
            //输入
            a = shuru(a);
            //比较
            max = Max(a);
            min = Min(a);
            sum = Sum(a);
            //输出
            shuchu(a, max, min, sum);
        }
        static void shuchu(int[] a, int max, int min, int sum)//输出函数式
        {
            double avg = 1.0 * (sum - max - min) / (a.Length - 2);
            Console.WriteLine("去掉一个最高分：{0}分；去掉一个最低分：{1}分；最终得分：{2}分。", max, min, avg);
        }
        static int[] shuru(int[] a)//输入函数式
        {
            for (int i = 0; i < 6; i++)
            {
                Console.Write("请{0}号裁判输入选手得分：", i + 1);
                a[i] = Convert.ToInt32(Console.ReadLine());
            }
            return a;
        }
        static int Max(int[] a)//比较函数式最大
        {
            int zd = 0;
            foreach (int b in a)
            {
                if (b > zd)
                {
                    zd = b;
                }
            }
            return zd;
        }
        static int Min(int[] a) //比较函数式最小
        {
            int zx = 1000;
            foreach (int b in a)
            {
                if (b < zx)
                {
                    zx = b;
                }
            }
            return zx;
        }
        static int Sum(int[] a)//比较函数式总和
        {
            int zf = 0;
            foreach (int b in a)
            {
                zf = zf + b;
            }
            return zf;
        }
