Count Even Elements in Array

Write a C# Sharp program to count the even number of elements in a given array of integers.

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
        {                
            // Outputting the result of the 'test' method with an integer array as an argument
            Console.WriteLine(test(new[] { 1, 5, 7, 9, 10, 12 })); 
        }           

        // Method to count the number of even integers in the given array
        static int test(int[] nums)
        {
            int evens = 0; // Initializing a counter to keep track of the even numbers

            // Looping through each element of the array
            for (int i = 0; i < nums.Length; i++)
            {
                // Checking if the current element is even (divisible by 2)
                if (nums[i] % 2 == 0)
                {
                    evens++; // Incrementing the counter if the element is even
                }
            }

            return evens; // Returning the total count of even numbers in the array
        }    
   }
}
