如何使用'for loop'数组'在c#

本文关键字:数组 loop for 何使用 | 更新日期: 2023-09-27 18:17:58

我是c#的新手,我正在学习反转整数(数字)。我必须使用forloop和数组来完成代码,但我真的不知道如何使用它们。
为例。如果输入为:1 2 3 4 5 6
结果应为:6 5 4 3 2 1

有人能帮帮我吗?谢谢你:)

我真的很抱歉,伙计们,我忘了添加代码。在这里。再次感谢
static void Main(string[] args)
{
    Console.WriteLine("Enter 6 Numbers");
    int numb = int.Parse(Console.ReadLine());
    int reverse = 0;
    while (numb > 0)
    {
        int rem = numb % 10;
        reverse = (reverse * 10) + rem;
        numb = numb / 10;
    }
    Console.WriteLine("The reverse is = {0}", reverse);
    Console.ReadLine();
}

这里一个字符串作为输入,需要反转。只是因为输入只是作为数字,所以这有点令人困惑。

如何使用'for loop'数组'在c#

除非您需要使用循环,否则更简单的解决方案是使用Array.Reverse:

int[] array = { 1, 2, 3, 4, 5, 6 };
Array.Reverse(array);

可以使用for循环迭代数组的一半,与数组另一边的位置交换位置。

int holder = 0;
int size = array.Length;
for (int i = 0; i < size / 2; ++i)
{
    holder = array[i];
    array[i] = array[size - 1 - i];
    array[size - 1 - i] = holder;
}

这是一个使用循环和使用数组来反转数字/整数的简单逻辑。反向功能

示例:输入12345将给我们输出54321

namespace PurushLogics
{
    class Purush_ReverseInteger
    {
        static void Main()
        {
            //Reverse a Number  
            int intstr;
            string intreverse = "";
            int intLength = 0;
            int? intj = null;
            Console.WriteLine("Enter a Number"); // Entering "12345" has input will return "54321" as output
            intstr = int.Parse(Console.ReadLine());//Getting integer from Console  
            char[] inta = intstr.ToString().ToCharArray();

            intLength = inta.Length - 1;
            for (int c = intLength; c >= 0; c--)
            {
                intreverse = intreverse + inta[c].ToString();
                intj = int.Parse(intreverse);
            }
            Console.WriteLine("Reverse Number is '"{0}'"", intj);//Displaying the reverse integer  
            Console.ReadLine();
            //Reverse integer using Array.Reverse
            Array.Reverse(inta);
            foreach (char reverse in inta)
            {
                Console.Write(reverse);
            }
            Console.ReadLine();
        }
    }
}
static void Main(string[] args)
        {
            int[] numbers = new int[6];
            for (int i = 0; i < 6; i++)
            {
                Console.Write("Number {0} : ", i + 1);
                numbers[i] = Convert.ToInt32(Console.ReadLine());
            }
            Console.WriteLine();
            for (int i = 5; i >= 0; i--)
            {
                Console.Write("{0} ", numbers[i]);
            }
            Console.ReadLine();
        }
   class Program
{
    static void Main(string[] args)
    {
        int[] array = new int[] { 1, 2, 3, 4, 5, 6,7};
        int temp = 0;
        for (int i = array.Length - 1; i >= (((array.Length - 1) % 2==0)? (((array.Length - 1) / 2)):((array.Length - 1) / 2)+1) ; i--)
        {
            temp = array[(array.Length - 1) - i];
            array[(array.Length - 1) - i] = array[i];
            array[i] = temp;
        }
        foreach (var p in array)
        {
            Console.WriteLine(p);
        }
        Console.ReadLine();
    }
}
int[] numbers=new int[]{1,2,3,4,5};
    int[] reverse=new int[numbers.Length];
    int j=numbers.Length-1;
    for(int i=0;i<numbers.Length;i++)
    {
        reverse[i]=numbers[j];
        Console.WriteLine(reverse[i]);
        j--;
    }
    public static int[] Test( params Int32[] nums)
    {
        int[] ar = new int[nums.Length];
        var count = 0;
        for (int i = nums.Length-1; i >= 0 ; i--)
        {
            ar[count] = nums[i];
            count++;
        }
        return ar;
    }
This is Palindrom or not  string tmp=""; string values = "";Console.Write("Please Enter Number : "); string strnumber = Convert.ToString(Console.ReadLine());  tmp = strnumber; if (strnumber.Length > 0)  { foreach (var res in strnumber.Reverse())  { values += res; } }  if (values == strnumber)  { Console.WriteLine("Number is Palindrome."); }  else { Console.WriteLine("Number is not Palindrome")
