nul in a sentence

Definition

NUL refers to a value or pointer that represents the absence of a valid or meaningful data entry or memory reference.

The software returned a NUL value when it encountered an empty field in the database.
In programming, a pointer that is set to NUL indicates that it does not reference any valid memory location.
When processing the data, the system replaced all missing entries with a NUL character for consistency.
The error message indicated a NUL pointer dereference, which caused the application to crash.
To avoid issues with data processing, ensure that any NUL inputs are properly handled before execution.
