Step by Step solution about How to resolve the algorithm Array length step by step in the C# programming language

1. Array Creation using Array Initializers:

   • var fruit = new[] { "apple", "orange" }; creates an array of strings named fruit with two elements: "apple" and "orange".
   • Array initializers provide a concise way to create and initialize arrays.

2. Array Length Property:

   • Console.WriteLine(fruit.Length); outputs the length of the fruit array, which is 2.
   • The Length property returns the number of elements in an array.

3. Multiple Ways to Declare and Initialize Arrays:

   • The following code snippets show alternative ways to declare and initialize arrays:
     • var fruit = new string[] { "apple", "orange" };
     • string[] fruit = new[] { "apple", "orange" };
     • string[] fruit = new string[] { "apple", "orange" };
     • string[] fruit = { "apple", "orange" };
   • All these declarations and initializations create an array of strings with two elements: "apple" and "orange".

4. Using **static** for Concise Syntax:

   • using static System.Console; imports the Console class into the current namespace, allowing you to use its members directly without specifying Console. prefix.
   • This results in a more concise syntax, as seen in the second Main method:
     • WriteLine(new[] { "apples", "oranges" }.Length);

using System;

class Program
{
    public static void Main()
    {
        var fruit = new[] { "apple", "orange" };
        Console.WriteLine(fruit.Length);
    }
}


var fruit = new[] { "apple", "orange" };
var fruit = new string[] { "apple", "orange" };
string[] fruit = new[] { "apple", "orange" };
string[] fruit = new string[] { "apple", "orange" };
string[] fruit = { "apple", "orange" };


using static System.Console;

class Program 
{
    public static void Main()
    {
        WriteLine(new[] { "apples", "oranges" }.Length);
    }
}
