What is nil zero?

Nil, also known as Null or None, is a term used in programming languages to indicate that a value does not exist or is empty. It is often represented by the keyword "nil" or "null".

Zero, on the other hand, is a numerical value that represents the absence of any quantity or amount. It is the additive identity and multiplicative identity of the real number system.

In some programming languages, Zero and Nil are different data types, but in others, they are considered the same. The concept of nil or zero is often used in conditional statements and loop structures to terminate a program or interrupt a process.
