c# - 如何在 C# 中为 "decimal to binary"修复此代码

Question

我在用 C# 的二进制公式输出公式时遇到问题

 static void Main(string[] args)
        {
            Console.Write("Input number : ");
            int num = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("The Formula : ");

            int accommodate = 0;

            for (int i = num; i > 0; i /= 2)
            {
                if (num % i == 0)
                {
                    accommodate++;

                    if (accommodate == 2)
                    {
                        Console.WriteLine(i + "/2 = 0");
                    }
                    else
                    {
                        Console.WriteLine(i + "/2 = 1" );
                    }

                }
            }
             Console.ReadKey();
        }

输出是

输入数字:12

公式:

12/2 = 1 "(X) 这是错误的，应该是0"

6/2 = 0

3/2 = 1

1/2 = 1

将你的代码改成这样

accommodate % 2 而不是 accommodate % i

在 for 循环中设置 accommodate = i/= 2 而不是 accommodate++

Console.Write("Input number : ");
            int num = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("The Formula : ");

            int accommodate = 0;

            for (int i = num; i > 0; accommodate = i /= 2)
            {
                if (accommodate % 2 == 0)
                {

                    Console.WriteLine(i + "/2 = 0");
                }
                else
                {
                    Console.WriteLine(i + "/2 = 1");
                }
            }
            Console.ReadKey();
