C# - How does a for loop understand the following syntax and why it works?

DOTNET FIDDLE

So, I left the for loop totally empty and did the following:

using System;

public class Program
{
    public static void Main()
    {
        int i = 0;
        for(;;){
            if(i < 5){
                Console.WriteLine(i);
                i++;
            }
            else
            {
                break;  
            }
        }
    }
}

I knew that it would work, but I don't know how why it works. Could someone explain to me why this works and how the for loop understands that syntax?

I'm new to C# so take it easy on me.

Each part of a for loop (;;) contains a statement. As you know first section for initialization then condition checking and finally the increment/decrement section.

If you leave them empty then the loop will iterate for infinite times like it happens for while(true).

There is no difference between for(;;) and while(true). You can use whatever you like.

A for(...) loop with no initialization, condition, iteration step for(;;) is an Infinite Loop which runs forever unless an explicit exit condition given
