上机练习2-
按规律生成输出一组数

上机练习3-
统计奇、偶数的个数

using System;

namespace demo13
{
    class Program
    {
    
    //两个都在里面
        class MyClass
        {
            public int[]  show()
            {
                int[] array = new int[30];
                array[0] = 1;
                array[1] = 1;
                for (int i = 2; i < array.Length; i++)
                {
                    array[i] = array[i - 1] + array[i - 2];
                }
                return array;
            }
            
            
}
        static void Main(string[] args)
        {
            MyClass class2=new MyClass();
            class2.show();
            int[] i =class2.show();
            int num=0;
            int num2=0;
            for (int j = 0; j < i.Length; j++)
            {
                Console.WriteLine(i[j]);
                if (i[j]%2==0)
                {
                    num++;
                }
                else
                {
                    num2++;
                }
            }
            Console.WriteLine("偶数{0}，奇数{1}",num,num2);
        }
