Question

C#输入一组非0整数（以0作为输入结束标志）到一维数组中，求出这一组数的平均值，统计出正数和负数的个数.

如，输入4，5，6，0，则输出 5
是C#的问题，求解

            int a = 1, num1 = 0, num2 = 0;

            float average = 0;  //a存储输入的整数，num1表示正数个数，num2表示负数个数,average表示平均数

            while (a != 0)

            {

                System.Console.Write("请输入一个整数(输入0表示输入结束):");

                a = Int32.Parse(System.Console.ReadLine());

                if (a > 0)

                {

                    num1++;

                    average += a;

                }

                else if (a < 0)

                {

                    num2++;

                    average += a;

                }

                else

                {

                    average = average / (num1 + num2);

                }

            }

            System.Console.WriteLine("平均数为："+average+"\t正数个数："+num1+"\t负数个数："+num2+"\n");

            Console.ReadLine();

int n;
int sum = 0;
int[] count=new int[1000];
int pos = 0;
int neg=0;
Console.WriteLine("请输入(以0作为输入结束标志)");
n = int.Parse(Console .ReadLine ());
for (int i = 0; n != 0;i++ )
{
count[i] = n;
sum = sum + n;
if (n > 0) pos++;
