Final answer:
An input validation loop is not called an error handler. It is used to validate user input and ensure the integrity and reliability of data in a program. An error handler is a section of code that handles errors or exceptions.
Step-by-step explanation:
An input validation loop is not called an error handler. An input validation loop is a programming construct used to validate user input and ensure that it meets certain criteria or conditions. It is used to prevent errors and ensure the integrity and reliability of data in a program.
An error handler, on the other hand, is a section of code or a subroutine that is designed to handle errors or exceptions that may occur during program execution. It is responsible for identifying, reporting, and recovering from errors or exceptions.
While an input validation loop can be part of an error handling mechanism, they are not the same thing. An input validation loop is focused on validating user input, whereas an error handler is focused on handling errors or exceptions that occur during program execution.
