清单上的快速问题 [英] Quick Question on Lists

问题描述

using System.Text;

namespace EvenandOdds
{
    class Program
    {
        static void Main(string[] args)
        {
            List<double> even = new List<double>();
            List<double> odd = new List<double>();

            Console.Write("odd: ");
            Random randomNums = new Random();

            for (int i = 0; i < 25; i++) ;
            {
                odd.Add(randomNums.Next(0,100));

                Console.WriteLine();

            }
             Console.ReadLine();

            }
        }
    }

我应该在最后一个WriteLine中显示什么以显示奇数?

What do I put in that last WriteLine to show the odd numbers?

推荐答案

好吧，您不必检查数字是否为奇数.为此，请执行以下操作:

Well, you do not check if the number is odd. To do that do something like :

bool isOdd = num % 2 != 0;

在此使用本地变量，然后将随机数分配给该本地变量.然后，您可以使用Console.WriteLine轻松显示它.或使用list[count - 1]访问最后一项.

Use a local variable there and assign the random number to this local. Then you can easily show it using Console.WriteLine. Or access the last item using list[count - 1].

您需要检查奇数，您可以使用 ^ ].

You need to check for odd numbers, which you can do with the % operator[^].

int Num = 5;

if(Num % 2 == 0)
{
  // It's even

}
else
{
  // It's odd

}
