Null vs. Void — What's the Difference?

Null in statistics represents the assumption of no statistical significance.

Void in programming means a function does not return a value.

In programming, null is a special marker used in place of an object.

Void in physics refers to a completely empty space.

In legal documents, null can render a document non-binding.

In everyday usage, void often means completely empty or ineffective.

Null is used to describe a void or absence in a broader sense.

Void can describe the nullification of an action or condition.

In databases, a null value indicates missing or unknown data.

Unassigned or meaningless; - a special value given to variables, especially pointers or logical variables, indicating that it is meaningless and cannot be used in computation; as, an uninitialized pointer in "C" is given a null value. The actual value that is stored in memory to indicate the null condition may vary with the computer language used.

Yes, null can broadly signify an absence or nonexistence in various contexts.

In programming, void specifies that a function returns no value, while in general use, it implies emptiness or ineffectiveness.

Some common synonyms for the term "null" include "nonexistent", "invalid" and "void".

Null in programming indicates a variable that holds no data and points to no object.

No, null represents a lack of data, whereas zero is a numeric value.

Void in legal documents means that the document has no legal effect or enforceability.

In physics, void describes an area completely devoid of matter.

A function itself cannot be null, but a function can return a null value or be a void type.

In statistics, null typically refers to a null hypothesis that assumes no effect or difference until proven otherwise.

If a legal agreement is declared void, it is treated as if it never existed and is unenforceable.
