Assign value to local variable

C# requires that local variable must have assigned value.

using System;

class Program
{
    static void Main(string[] args)
    {
        int i;
        Console.WriteLine(i);

    }
}

Compile the code above:

Microsoft (R) Visual C# 2010 Compiler version 4.0.30319.1

Program.cs(8,27): error CS0165: Use of unassigned local variable 'i'

To fix the problem, assign a value to the local variable i.

using System;

class Program
{
    static void Main(string[] args)
    {
        int i = 5;
        Console.WriteLine(i);


    }
}

We don't need to initialize each elements in an array explicitly, since array elements are initialized by C#.
