How to fix 'Use of unassigned local variable' in C# : <p>I am new to C#, my last programming language was C</p>

<p>I kept getting Use of unassigned local variable 'average'
The <code>average</code> it is pertaining was the <code>average /= 10;</code></p>

<pre><code>using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            int i, average;
            int[] scores = new int[10];

            Console.WriteLine("Enter 10 scores");
            for (i = 0; i &lt; 10; i++)
            {
                scores[i] = Convert.ToInt32(Console.ReadLine());
            }

            for (i = 0; i &lt; 10; i++)
            {
                average = scores[i] + scores[i + 1];
                i++;
            }

            average /= 10;

            Console.WriteLine("Average of All the Scores: {0}", average);
            Console.Read();
        }
    }
}
</code></pre>
