How to reverse a given number in C#?

In the following C# program, we take the input number from the console and then reverse that number.

using System; namespace LogicalPrograms < public class Program < static void Main(string[] args) < Console.Write("Enter a Number : "); int number = int.Parse(Console.ReadLine()); int reminder, reverse = 0; while (number >0) < //Get the remainder by dividing the number with 10 reminder = number % 10; //multiply the sum with 10 and then add the reminder reverse = (reverse * 10) + reminder; //Get the quotient by dividing the number with 10 number = number / 10; >Console.WriteLine($"The Reverse order is : "); Console.ReadKey(); > > >

How to reverse a string in C#?

In the following C# program, we take the string as an input from the console. Then we reverse the string using for loop.

using System; namespace LogicalPrograms < public class Program < static void Main(string[] args) < Console.Write("Enter a String : "); string name = Console.ReadLine(); string reverse = string.Empty; for (int i = name.Length - 1; i >= 0; i--) < reverse += name[i]; >Console.WriteLine($"The Reverse string is : "); Console.ReadKey(); > > >

Output:

Reverse a string Using Foreach loop in C#:

Let us see how to reverse a string using for each loop in C#.

using System; namespace LogicalPrograms < public class Program < static void Main(string[] args) < Console.Write("Enter a String : "); string name = Console.ReadLine(); string reverse = string.Empty; foreach (char c in name) < reverse = c + reverse; >Console.WriteLine($"The Reverse string is : "); Console.ReadKey(); > > >

Output:

Reverse a string using Array.Reverse Method in C#:

In the following example, we take a string as an input from the console and then convert that string to a character array. Then we use the Array class Reverse method to reverse the elements of the character array. Once we reverse the elements of the character array, then we create a string from that character array.

using System; namespace LogicalPrograms < public class Program < static void Main(string[] args) < Console.Write("Enter a String : "); string name = Console.ReadLine(); char[] nameArray = name.ToCharArray(); Array.Reverse(nameArray); string reverse = new string(nameArray); Console.WriteLine($"The Reverse string is : "); Console.ReadKey(); > > >

In the next article, I am going to discuss the Armstrong Number Program in C# with some examples. Here, in this article, I try to explain the different ways to Reverse a Number and a String in C# with examples. I hope you enjoy this Reverse a Number and a String in C# article.

Как перевернуть число?

Пользователь вводит с клавиатуры число, необходимо перевернуть его (число) и вывести на экран.

Примечание: Например, пользователь ввел число 12345. На экране должно появиться число наоборот — 54321.

Как перевернуть число?
Как перевернуть число? Пример: 1210 — 1012

Как перевернуть число?
как перевернуть любое число в Паскале ?

Как перевернуть число
как перевернуть число? например: 0123450=0543210

Как перевернуть натуральное число?
Было 12345 Стало 54321

ИМХО Полученную строку разбиваем на массив символов и выводим этот массив в обратной последовательности

int a = 123; string s = a.ToString(); char[] ar = s.ToCharArray(); Array.Reverse(ar); s = new String(ar); a = Convert.ToInt32(s);

const S: string = '12345'; var i: byte; R: string; Begin R:=''; For i:=length(S) downto 1 do R:=R+S[i]; Writeln(R); End.

Сообщение от only#

int a = 123; string s = a.ToString(); char[] ar = s.ToCharArray(); Array.Reverse(ar); s = new String(ar); a = Convert.ToInt32(s);

А вообще желательно что бы использовали числа от 0 до 5 , и можно было написать любое значное число из этих цифр, и он их переворачивал

1 2 3 4 5 6 7 8 9 10 11 12 13

static void Main(string[] args) { Console.WriteLine("Число"); string s = Console.ReadLine(); char[] str = s.ToCharArray();; string a; for (int i = str.Length-1; i > -1; --i) { a = Convert.ToString(str[i]); Console.Write(a); } Console.ReadKey(); }

Сообщение от vauper

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

static void Main(string[] args) { int number, result = 0; Console.Write("enter number: "); number = Int32.Parse(Console.ReadLine()); while (number > 0) { result *= 10; result += number % 10; number /= 10; } Console.WriteLine(result); }

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

static class IntExt { public static int Reverse(this int i) { int res = 0; while (i != 0) { int remaind; i = Math.DivRem(i, 10, out remaind); res = res * 10 + remaind; } return res; } } int i = 12345.Reverse();

введите 010.
Загадка: это разные числа, или одно число?

00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000000000000000000000000000000000000000000000000000000 00000000000000000000000000000010
