Set the unsorted array first.int[] list = {87, 45, 56, 22, 84, 65};Now use a nested for loop to sort the list, which is passed to a function.for(int i=0; i< arr.Length; i++) { for(int j=i+1; j=arr[j]) { temp=arr[j]; arr[j]=arr[i]; arr[i]=temp; } } Console.Write(arr[i] + " "); }The following is the complete code to sort one-dimensional array in ascending order using non-static method.Example Live Demousing System; namespace Demo { public class MyApplication { public static void Main(string[] args) { ...

Declare Jagged ArrayA Jagged array is an array of arrays. You can declare a jagged array named scores of type int as −int [][] points;Initialize Jagged ArrayLet us now see how to initialize it.int[][] points = new int[][]{new int[]{10, 5}, new int[]{30, 40}, new int[]{70, 80}, new int[]{ 60, 70 }};Access the Jagged Array ElementAccess the jagged array element as.points[i][j]);The following is the complete example showing how to work with jagged arrays in C#.Example Live Demousing System; namespace ArrayApplication { class MyArray { static void Main(string[] args) { int[][] points = new int[][]{new ...

The Sort() method sorts the elements in an entire one-dimensional Array using the IComparable implementation of each element of the Array.Set the array.int[] list = { 22, 12, 65, 9};Use the Sort() method to sort the array.Array.Sort(list);The following is an example to learn how to work with the Sort() method.Example Live Demousing System; namespace Demo { class Program { static void Main(string[] args) { int[] list = { 22, 12, 65, 9}; Console.Write("Original Array: "); foreach (int i in list) { ...

The ToString() method returns a string that represents the current object.In the below example, we have used the ToString() method with another Array class method.arr.GetLowerBound(0).ToString()Example Live Demousing System; using System.Collections.Generic; using System.Linq; using System.Text; namespace lower { class Program { static void Main(string[] args) { Array arr = Array.CreateInstance(typeof(String), 3); arr.SetValue("One", 0); arr.SetValue("Two", 1); Console.WriteLine("Lower Bound {0}",arr.GetLowerBound(0).ToString()); Console.ReadLine(); } } }OutputLower Bound 0
WriteLine() is a method of the Console class defined in the System namespaceThis statement causes the message "Welcome!" to be displayed on the screen as shown below −Example Live Demousing System; namespace Demo { class Test { static void Main(string[] args) { Console.WriteLine("Welcome!"); Console.ReadKey(); } } }OutputWelcome!To display a char array using the Console.WriteLine.Example Live Demousing System; namespace Demo { class Test { static void Main(string[] args) { char[] arr = new char[] { 'W', 'e'}; Console.WriteLine(arr); Console.ReadKey(); } } }OutputWe
Firstly, set a list in C#.var list = new List{ "one","two","three","four"};Now get the count of the elements and display randomly.int index = random.Next(list.Count); Console.WriteLine(list[index]);To select a random element from a list in C#, try to run the following code −Example Live Demousing System; using System.Collections.Generic; namespace Demo { class Program { static void Main(string[] args) { var random = new Random(); var list = new List{ "one","two","three","four"}; int index = random.Next(list.Count); Console.WriteLine(list[index]); } } }Outputthree

const_castcan be used to remove or add const to a variable. This can be useful if it is necessary to add/remove constness from a variable.static_castThis is used for the normal/ordinary type conversion. This is also the cast responsible for implicit type coersion and can also be called explicitly. You should use it in cases like converting float to int, char to int, etc.dynamic_castThis cast is used for handling polymorphism. You only need to use it when you're casting to a derived class. This is exclusively to be used in inheritence when you cast from base class to derived class.reinterpret_castThis is ... Read More
The assignment consists of 2 steps, tearing an object's old state and building a new state for it. The destructor is used for the first step and a copy constructor does the second step. Implementing both of these is straightforward. But when overloading the assignment operator, it can become quite difficult to implement. The copy and swap idiom is a solution for the same.This idiom uses the copy-constructor to build a local copy of the data. It then swaps the old data with the new data using the swap function. The temporary copy is then destructed using the destructor. We ... Read More
ReferencesWhen a variable is declared as a reference, it becomes an alternative name for an existing variable.Syntax Type &newname = existing name;InitializationType &pointer; pointer = variable name;PointersPointers are used to store the address of a variable.SyntaxType *pointer;InitializationType *pointer; pointer = variable name;The main differences between references and pointers are -References are used to refer an existing variable in another name whereas pointers are used to store the address of a variable.References cannot have a null value assigned but pointer can.A reference variable can be referenced bypass by value whereas a pointer can be referenced but pass by referenceA reference must ...
