            string[] str = { "Ravi", "Ram", "Raj", "Rahul", "Raheem" };

            Console.WriteLine("Original array: ");

            for (int i = 0; i < str.Length; i++)

            {

                Console.Write(str[i] + " ");

            }

            Console.WriteLine("\n");

            str[1] = "Raj";

                        str[2] = "Ram";

            Console.WriteLine("Modified array: ");

            for (int i = 0; i < str.Length; i++)

            {

                Console.Write(str[i] + " ");

            }

            Console.ReadLine();

8) Reverse array array[]{“Ravi”, ”Ram”, “Raj”, “Rahul”, “Raheem”}

            Console.WriteLine("Given Array : ");

            string[] array = { "Ravi", "Ram", "Raj", "Rahul", "Raheem" };

            foreach (var a in array)

            {

int[] arr = new int[] { 24, 22, 33, 23, 76, 87, 51 };

Console.WriteLine("Given Array: ");

foreach (int value in arr)

 {

Console.WriteLine(value + " ");

        }

       Console.WriteLine("Ascending order: \n");
