# C#: Check specific digit in an array of numbers

## C# Sharp Array: Exercise-38 with Solution

Write a C# Sharp program that takes an array of numbers and a digit. Check whether the digit is present in this array of numbers.

Sample Data:
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Present"
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Present"
({7, 5, 85, 9, 11, 23, 18}, "1") - > "Not present..!"

Sample Solution:

C# Sharp Code:

``````using System;
using System.Linq;
namespace exercises
{
class Program
{
static void Main(string[] args)
{
int[] nums = { 7, 5, 85, 9, 11, 23, 18 };
string n = "1";
Console.WriteLine("Original array elements:");
Console.WriteLine(\$"{string.Join(", ", nums)}");
Console.WriteLine("\nDigit to search: " + n);
Console.WriteLine("Check the said digit present in the array!: " +test(nums, n));
n = "9";
Console.WriteLine("\nDigit to search: " + n);
Console.WriteLine("Check the said digit present in the array!: " + test(nums, n));
n = "4";
Console.WriteLine("\nDigit to search: " + n);
Console.WriteLine("Check the said digit present in the array!: " + test(nums, n));
}
public static string test(int[] nums, string n)
{
return nums.Select(s => \$"{s}").Any(a => a.Contains(n)) ? "Present" : "Not present..!";
}
}
}
```
```

Sample Output:

```Original array elements:
7, 5, 85, 9, 11, 23, 18

Digit to search: 1
Check the said digit present in the array!: Present

Digit to search: 9
Check the said digit present in the array!: Present

Digit to search: 4
Check the said digit present in the array!: Not present..!
```
