Arrays in C#

Arrays:

An array stores a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, ..., and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and ..., numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

using System.Collections.Generic;

using System.Linq;

using System.Threading.Tasks;

namespace Practice

{

    class Program

    {

        static void Main(string[] args)

        {

Arrays c = new Arrays ();

c. array ();

              Console.ReadLine();

        }

    }

}

using System.Threading.Tasks;

namespace Practice

{

    class Arrays

    {

        public void array()

        {

            //using for loop

            int[] n = new int[10];

            int i, j;

            for (i = 0; i < 10; i++)

            {

                n[i] = i + 100;

            }

            for (j = 0; j < 10; j++)

            {

                Console.WriteLine("the element of array are {0}={1}", j, n[j]);

            }

            //using foreach loop

            foreach (int a in n)

            {

                int c = a - 100;

                Console.WriteLine("elements are {0}={1}", c, a);

                c++;

            }

            Console.ReadKey();

        }

    }

}
