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
        {               
            // Calling the 'test' method with a given integer array and storing the returned array in 'item'
            int[] item = test(new[] { 1, 2, 3, 5, 7 }); 

            // Outputting the elements of the new array formed before the element '5' if found
            Console.Write("New array: "); 
            foreach (var i in item) // Looping through each element in the 'item' array
            {
                Console.Write(i.ToString() + " "); // Outputting each element followed by a space
            }     
        }               

        // Method to extract elements of an array before the occurrence of the value '5'
        static int[] test(int[] numbers)
        {
            int size = 0; // Variable to store the size of the elements before '5'
            int[] pre_ele_5; // Array to hold the elements before '5'

            // Looping through the array to find the index where '5' occurs
            for (int i = 0; i < numbers.Length; i++)
            {
                if (numbers[i] == 5)
                {
                    size = i; // Storing the index where '5' is found
                    break;
                }
            }

            pre_ele_5 = new int[size]; // Creating an array with size determined before '5'

            // Storing elements before '5' into the pre_ele_5 array
            for (int j = 0; j < size; j++)
            {
                pre_ele_5[j] = numbers[j];
            }

            return pre_ele_5; // Returning the array containing elements before '5'
        }    
    } 
}

Sample Output:

New array: 1 2 3
