﻿ C# - New array taking the first two elements from a array

# C#: Create a new array taking the first two elements from a given array

## C# Sharp Basic Algorithm: Exercise-108 with Solution

Write a C# Sharp program to create an array by taking the first two elements from an array. If the given array length is shorter than 2, return the given array.

Visual Presentation:

Sample Solution:-

C# Sharp Code:

``````using System; // Importing the System namespace

namespace exercises // Defining a namespace called 'exercises'
{
class Program // Defining a class named 'Program'
{
static void Main(string[] args) // The entry point of the program
{
// Testing the 'test' method with an integer array as an argument and displaying the resulting array
int[] item = test(new[] { 1, 5, 7, 9, 11, 13 });

// Outputting text to indicate the start of displaying the new array
Console.Write("New array: ");

// Looping through each element of the 'item' array and displaying them
foreach(var i in item)
{
Console.Write(i.ToString()+" "); // Displaying each element of the 'item' array separated by a space
}
}

// Method to create and return a new array containing the first one or two elements of the input array
static int[] test(int[] numbers)
{
int[] front_nums; // Declaring an array to store the first one or two elements

// Checking the length of the input array to determine the elements to be included in the new array
if (numbers.Length >= 2)
{
front_nums = new int[] { numbers[0], numbers[1] }; // Creating an array with the first two elements
}
else if (numbers.Length > 0)
{
front_nums = new int[] { numbers[0] }; // Creating an array with the only available element
}
else
{
front_nums = new int[0]; // Creating an empty array if there are no elements in the input array
}

return front_nums; // Returning the new array containing the selected elements
}
}
}
```
```

Sample Output:

`New array: 1 5`
