Find frequency of each word in a string in C#
To find the frequency of each word in a string, you can try to run the following code −Example Live Demousing System; class Demo { static int maxCHARS = 256; static void calculate(String s, int[] cal) { for (int i = 0; i < s.Length; i++) cal[s[i]]++; } public static void Main() { String s = "Football!"; int []cal = new int[maxCHARS]; calculate(s, cal); for (int i = 0; i < maxCHARS; i++) if(cal[i] > ...
Read MoreHow to find Volume and Surface Area of a Sphere using C#?
For volume and surface area of a sphere, firstly declare a variable with the value of radius.int r = 15;Get the volume f the sphere.// calculating volume of sphere cal_volume = (4.0 / 3) * (22 / 7) * r * r * r;Now the surface area of the sphere is calculated −cal_area = 4 * (22 / 7) * r * r;Let us see the complete code −Example Live Demousing System; using System.Collections.Generic; public class Demo { public static void Main(string[] args) { double cal_area, cal_volume, r; // radius ...
Read MoreHow to find the average of elements of an integer array in C#?
The following is our integer array −int[] myArr = new int[6] { 8, 4, 2, 5, 9, 14 };Firstly, get the length of the array, and loop through the array to find the sum of the elements. After that, divide it with the length.int len = myArr.Length; int sum = 0; int average = 0; for (int i = 0; i < len; i++) { sum += myArr[i]; } average = sum / len;Here is the complete codeExample Live Demousing System; public class Program { public static void Main() { ...
Read MoreHow to find the product of two binary numbers using C#?
To find the product of two binary numbers, firstly set them.val1 = 11100; val2 = 10001; Console.WriteLine("Binary one: "+val1); Console.WriteLine("Binary two: "+val2);Now loop through to get the product.while (val2 != 0) { digit = val2 % 10; if (digit == 1) { val1 = val1 * factor; prod = displayMul(val1, prod); } else val1 = val1 * factor; val2 = val2 / 10; factor = 10; } Console.WriteLine("Product = {0}", prod);Above a method displayMul() is called with the first binary number.static long displayMul (long val1, long val2) ...

Set the first list.int[] arr1 = { 65, 57, 63, 98 };Now, set the second list.int[] arr2 = { 43, 65, 33, 57 };Let us now see the complete code to check if two lists have common elements using == and < operators.Example Live Demousing System; using System.Collections.Generic; using System.Linq; public class Program { public static void Main() { int[] arr1 = { 65, 57, 63, 98 }; ...
Read MoreC# program to print unique values from a list
Set the list.List < int > list = new List < int > (); list.Add(99); list.Add(49); list.Add(32);To get unique elements.List myList = list.Distinct().ToList();Here is the complete example to display unique values from a list.Example Live Demousing System; using System.Collections.Generic; using System.Linq; public class Demo { public static void Main() { List < int > list = new List < int > (); list.Add(55); list.Add(45); list.Add(55); list.Add(65); list.Add(73); list.Add(24); list.Add(65); Console.WriteLine("Initial List..."); ...
Read MoreWhat is the Mutex class in C#?
The Mutex class in C# is a synchronization primitive that can also be used for interprocess synchronization.Let us see how to create a new Mutex.private static Mutex m = new Mutex();Let us now see how to initialize a new instance of the Mutex class with a Boolean value.private static Mutex m = new Mutex(true);Now let us see how to initialize a new instance of the Mutex class with a Boolean value and the name of the Mutex.Example Live Demousing System; using System.Threading; public class Demo { public static void Main() { Mutex mt = new Mutex(false, ...
Read MoreSorting a String in C#
Firstly, set a string array.string[] values = { "tim", "amit", "tom", "jack", "saurav"};Use the Sort() method to sort.Array.Sort(values);Let us see the complete code −Example Live Demousing System; public class Program { public static void Main() { string[] values = { "tim", "amit", "tom", "jack", "saurav"}; foreach (string value in values) { Console.Write(value); Console.Write(' '); } // sorting Array.Sort(values); Console.WriteLine("Sorted..."); foreach (string value in values) { Console.Write(value); Console.Write(' '); } Console.WriteLine(); } }Outputtim amit tom jack saurav Sorted... amit jack saurav tim tom
Read MoreC# program to split the Even and Odd integers into different arrays
Take two arrays:int[] arr2 = new int[5]; int[] arr3 = new int[5];Now, if the array element gets the remainder 0 on dividing by 2, it is even. Get those elements and add in another array. This loops through the length of the array:if (arr1[i] % 2 == 0) { arr2[j] = arr1[i]; }In the else condition, you will get the odd elements. Add them to a separate array and display them individually as shown in the below example:Example Live Demousing System; namespace Demo { public class Program { public static void Main(string[] args) { ...
