This was intended as a meme but is actually a good representation of what "Null" is. In C#, when you declare string s = "My shit"; it means that "s" is a reference to a memory location that holds the data "My shit". string s = null; means that the reference "s" exists but it's not pointing to any object, as in it holds nothing.

Suppose I send you a letter and ask you a question. a) If you send me back the letter with nothing written on it --> empty string b) If you don't send anything back --> NULL EDIT: To incorporate what u/glutier said: In scenario a, I would be able to compare your answer with others (and maybe group you with others who have no opinion on the matter). Whereas in scenario B, I cannot assume anything about your response and therefore cannot compare you to anyone. More on reddit.com

March 21, 2023Why the hate for null?
Null pointer exceptions are annoying but so is having to constantly check every object Very few values in your program actually need to be nullable, so you only need to check those places where they are. And you should be checking those places anyway! Edit: Note that you might be missing the important fact that you need some way for the compiler to remember that you've done the check. You can do this by pattern matching or flow-sensitive typing, for example. But yeah, this means you don't have to keep going back to check, which would be super annoying! It's also a shame to see the level of negativity in the other comments. It's really useful to hear perspectives like this, because it helps us see how other people might misunderstand what we are doing, and can help improve our explanations. Let's be a little friendlier please! :) More on reddit.com

NULL is nothing. It means theres nothing there. Often its just a place holder before something is there. Say u have a bunch of variables of animals. U might set them to NULL before u know what they are. Then u might check if they are NULL before u add an animal to them. Things are initialized as NULL.

I am a software engineer but my boss isn't. I understand the difference between a null value and, say, an empty string but myself and the other programmers are unable to explain that in a way someone with business experience can understand. Please help me explain like I'm five what Null is and how it differs from the empty string.
EDIT: I love the analogy. This is a good explanation. Answer
