Which term refers to an unintentional input that causes an error in a program?

The term that refers to an unintentional input that causes an error in a program is 'erroneous data.' This term captures the idea that the data being fed into a program is flawed or incorrect, which can lead to unexpected behavior or errors during execution. Erroneous data could stem from user input mistakes, data corruption, or any other source that might compromise the integrity of the input values.

Other terms mentioned might relate to errors but do not specifically denote unintentional input errors. For example, runtime errors typically occur during the execution of a program due to issues that are discovered only while the program is running, which is broader than just concerns about the validity of input. Input errors can imply misformatted or invalid inputs but do not necessarily encapsulate the broader context of data integrity that 'erroneous data' includes. Logic errors refer to flaws in the program's design which lead to incorrect output but are not directly about input itself.
