Why would someone use the << operator in an enum declaration?

Question

I was looking at the code I have currently in my project and found something like this:

public enum MyEnum
{
    open     = 1 << 00,
    close    = 1 &         


        

Answer 1

It's just meant to be a cleaner / more intuitive way of writing the bits. 1, 2, 3 is a more human-readable sequence than 0x1, 0x2, 0x4, etc.
