Write an application that can hold five integers in an array. display the integers from first to last, and then display the integers from last to first.

Create an integer array which holds five integers

Explanation:

I have written a simple program using c# as a programming language.

Here's  the  program:

using System;

public class Test

{

   public static void Main()

   {

       int[] numbers = new int[5];

       Console.WriteLine("enter 5 numbers");

       for (int i=0; i<=4; i++)

       {

          numbers[i]= Convert.ToInt32(Console.ReadLine());

       }

       foreach(int k in numbers)

       {

           Console.WriteLine(k+ "\n");

       }

       Console.WriteLine("----------------------------");

       Console.WriteLine("In reverse");  

       for(int j=4; j>=0; j--)

       {

           Console.WriteLine(numbers[j] + "\n");

       }

       Console.ReadLine();

   }      

}

Explanation of Program:

I have created an array named "numbers"  and assigned 5 as it's fixed size.

I prompted the user to enter numbers up to 5. I read those input numbers using Console.ReadLine() and converted to integers as return type of  Console.ReadLine() is string. I have stored all inputs from user into an array  while reading as below:

    numbers[i]= Convert.ToInt32(Console.ReadLine());

Next step is to print them. We can do it easily using foreach loop where it pulls out elements from an array until it reaches  end of an array and print them on console.

If I need to print them from first to last, the condition is,

    for (int i=0; i<=4; i++)  

as it needs to start from first element

If I need to print them from last to first, the condition is,

    or(int j=4; j>=0; j--)  

as it needs to start from last element
