# Print all Odd numbers from array of integers using C# program

This is a C# program, which will use to print all ODD numbers from an array of integers, to find the Odd number; we will check the remainder of each element b dividing 2, if the remainder is not 0 that means elements are ODD.

Given array of integers, and we have to print all ODD numbers.

For example we have list of integers:

```18, 13, 23, 12, 27

18 is properly divisible by 2, So it is a not odd number.
13 is not properly divisible by 2, so it is a odd number.
23 is not properly divisible by 2, so it is a odd number.
12 is properly divisible by 2, So it is not a odd number.
27 is not properly divisible by 2, so it is a odd number.
```

Consider the example:

```using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
class Program
{
static void Main()
{
int i       = 0;
//declaring array of integers
int[] arr   = new int;

Console.WriteLine("Enter array elements : ");
for (i = 0; i < arr.Length; i++)
{
Console.Write("Element[" + (i + 1) + "]: ");
}

//checking and printing all odd numbers
Console.WriteLine("List of odd  numbers : ");
for (i = 0; i < arr.Length; i++)
{
//condition to check ODD number
if (arr[i] % 2 != 0)
Console.Write(arr[i] + " ");
}
Console.WriteLine();
}
}
}
```

Output

```Enter array elements :
Element: 10
Element: 11
Element: 12
Element: 13
Element: 14
List of odd  numbers :
11 13
```
