Check Odd Number in Array

Write a C# program to check if an array contains an odd number.

Pictorial Presentation:

Sample Solution:

C# Sharp Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

public class Exercise53
{  
    public static void Main() 
    {
        // Initializing an array of integers
        int[] nums = {2, 4, 7, 8, 6};

        // Displaying the original array
        Console.WriteLine("\nOriginal array: [{0}]", string.Join(", ", nums));

        // Checking if the array contains an odd number and displaying the result
        Console.WriteLine("Check if an array contains an odd number? " + even_odd(nums));
    }  

    // Function to check if the array contains an odd number
    public static bool even_odd(int[] nums)  
    {
        // Iterating through each element of the array
        foreach (var n in nums)
        {
            // Checking if the element is odd
            if (n % 2 != 0) 
                return true; // If an odd number is found, return true
        }
        return false; // If no odd number is found, return false
    } 
}

Sample Output:

Original array: [2, 4, 7, 8, 6]                                        
Check if an array contains an odd number? True
