Firstly, set the two numbers to be multiplied.val1 = 10; val2 = 20;Now cal the method to find the product.product(val1, val2);Under the product method, a recursive call will get you the product.val1 + product(val1, val2 – 1)Let us see the complete code to find the product of 2 numbers using recusion.Exampleusing System; class Calculation { public static void Main() { int val1, val2, res; // the two numbers val1 = 10; val2 = 20; // finding product Demo d = new ...

To get the sum of digits using recursion, set a method in C# that calculates the sum.static int sum(int n) { if (n != 0) { return (n % 10 + sum(n / 10)); } else { return 0; }The above method returns the sum and checks it until the entered number is not equal to 0.The recursive call returns the sum of digits o every recursive call −return (n % 10 + sum(n / 10));Let us see the complete code −Example Live Demousing System; class Demo { public static void ...

To find the average values, firstly set an arrayLint[] myArr = new int[10] { 45, 23, 55, 15, 8, 4, 2, 5, 9, 14 };Now find the sum and divide it by the length of the array to get the average.int len = myArr.Length; int sum = 0; int average = 0; for (int i = 0; i < len; i++) { sum += myArr[i]; average = sum / len; }Let us see the complete code −Exampleusing System; public class Program { public static void Main() { int[] myArr = new int[10] { 45, 23, 55, 15, 8, 4, 2, 5, 9, 14 }; int len = myArr.Length; int sum = 0; int average = 0; for (int i = 0; i < len; i++) { sum += myArr[i]; } average = sum / len; Console.WriteLine("Sum = " + sum); Console.WriteLine("Average Of integer elements = " + average); } }
