Firstly, set an array −int[] arr = { 87, 55, 23, 87, 45, 23, 98 };Now declare a dictionary and loop through the array and get the count of all the elements. The value you get from the dictionary displays the occurrence of numbers −foreach(var count in arr) { if (dict.ContainsKey(count)) dict[count]++; else dict[count] = 1; }Let us see the complete example −Exampleusing System; using System.Collections.Generic; namespace Demo { public class Program { public static void Main(string[] args) { ...

Let’s say the following is our float −float n = 50.5f;Take an empty string to display the binary value and loop until the value of our float variable is greater than 1 −string a = ""; while (n >= 1) { a = (n % 2) + a; n = n / 2; }Let us see the complete example −Example Live Demousing System; using System.IO; using System.CodeDom.Compiler; namespace Program { class Demo { static void Main(string[] args) { // float to binary Console.WriteLine("float to binary = "); float n = 50.5f; string a = ""; while (n >= 1) { a = (n % 2) + a; n = n / 2; } Console.Write(a); } } }Outputfloat to binary = 1.5781251.156250.31250.6251.250.5

Declare a 2D array −int[] a = new int[] { 65, 45, 32, 97, 23, 75, 59 };Let’s say you want the Kth smallest i.e, 5th smallest integer. Sort the array first −Array.Sort(a);To get the 5th smallest element −a[k - 1];Let us see the complete code −Exampleusing System; using System.IO; using System.CodeDom.Compiler; namespace Program { class Demo { static void Main(string[] args) { int[] a = new int[] { 65, 45, ...

To check if a string is a valid keyword, use the IsValidIdentifier method.The IsValidIdentifier method checks whether the entered value is an identifier or not. If it’s not an identifier, then it’s a keyword in C#.Let us see an example, wherein we have set the CodeDomProvider and worked with the IsValiddentifier method −CodeDomProvider provider = CodeDomProvider.CreateProvider("C#");Let us see the complete codeLExample Live Demousing System; using System.IO; using System.CodeDom.Compiler; namespace Program { class Demo { static void Main(string[] args) { string str1 = "amit"; string str2 = ...

Firstly, create an instance of DriveInfo −DriveInfo dInfo = new DriveInfo("E");Display free space −Console.WriteLine("Disk Free space = {0}", dInfo.AvailableFreeSpace); Now, use AvailableFreeSpace property and get the percentage of free space −Double pc = (dInfo.AvailableFreeSpace / (float)dInfo.TotalSize) * 100;Here, you will get the percentage of free size in comparison with the total disk space −Console.WriteLine(" Free space (percentage) = {0:0.00}%.", pc);
