How 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 codeExampleusing System; public class Program { public static void Main() { int[] ...

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) ...

Firstly, set a jagged array.int[][] arr = new int[][] { new int[] { 0, 0 }, new int[] { 1, 2 }, new int[] { 2, 4 }, new int[] { 3, 6 }, new int[] { 4, 8 } };Now, use the GetLowerBound(), GetUpperBound() and Rank property to get the lenth and rank of the array as shown in the following code ...
Read MoreHow to find the Rank of a given Array in C#?
To find the rank of an array, use the Rank property.Firstly, declare and initialize an array.int[,] myArr = new int[3,3];Now, get the rank.myArr.RankLet us see the complete code −Exampleusing System; class Demo { static void Main() { int[,] myArr = new int[3,3]; Console.WriteLine("Rank of Array : " + myArr.Rank); } }OutputRank of Array : 2

Declare and initialize a list.var products = new List (); products.Add("Accessories"); products.Add("Clothing"); products.Add("Footwear");To get the size, use the Capacity property.products.CapacityNow let us see the complete code to find the size of a list.Exampleusing System; using System.Collections.Generic; public class Demo { public static void Main(string[] args) { var products = new List (); products.Add("Accessories"); products.Add("Clothing"); products.Add("Footwear"); Console.WriteLine("Our list...."); foreach(var p in products) { Console.WriteLine(p); } Console.WriteLine("Size of list = " + products.Capacity); } }OutputOur list.... Accessories Clothing Footwear Size of list = 4
