How to print one dimensional array in reverse order?
Firstly, declare and initialize one dimensional array.int[] arr = { 35, 12, 66, 90, 34, 2, 64 };Now, use the following to reverse −Array.Reverse(arr);The following is the complete code to reverse a one-dimensional array;Exampleusing System; class Demo { static void Main() { int[] arr = { 76, 12, 66, 90, 34, 2, 64 }; // Initial Array Console.WriteLine("Original Array= "); foreach (int i in arr) { Console.WriteLine(i); } // Reverse Array Array.Reverse(arr); Console.WriteLine("Reversed Array= "); foreach (int j in arr) { Console.WriteLine(j); } Console.ReadLine(); } }OutputOriginal Array= 76 12 66 90 34 2 64 Reversed Array= 64 2 34 90 66 12 76

Set a list.List myList = new List(){1, 2, 3, 5, 8, 9};Now, get the first and last elements −int a = myList.OrderBy(x => x).First(); int b = myList.OrderBy(x => x).Last();In a new list, get all the elements and use the Except to get the missing numbers −List myList2 = Enumerable.Range(a, b - a + 1).ToList(); List remaining = myList2.Except(myList).ToList();Let us see the complete code −Exampleusing System.Collections.Generic; using System; using System.Linq; public class Program { public static void Main() { List myList = new List(){1, 2, 3, 5, 8, 9}; Console.WriteLine("Numbers... "); ...

We are open 365 days in a year!");Use the Success property now to display the result if number is found in the string as shown in the following complete code −Exampleusing System; using System.Text.RegularExpressions; class Demo { static void Main() { Regex r = new Regex(@"\d+"); Match m = r.Match("Welcome!

It is called Prefix increment operator. In the same way the decrement operator works but it decrements by 1.For example, ++a;The following is an example demonstrating Prefix increment operator −Exampleusing System; class Program { static void Main() { int a, b; a = 10; Console.WriteLine(++a); b = a; Console.WriteLine(a); Console.WriteLine(b); } }Output11 11 11
