Question

Which programmed input validation makes sure that a value was entered in all of the critical fields?

a. Completeness Check
b. Validity check
c. Reasonableness Check
d. Field Check

Answer 1

The programmed input validation that ensures a value is entered in all critical fields is a 'Completeness Check'. It verifies each required field has been filled. The other checks have different purposes not specifically tied to checking for empty fields.

Step-by-step explanation:

The correct answer to the student's question, "Which programmed input validation makes sure that a value was entered in all of the critical fields?" is a. Completeness Check.

A completeness check is a type of input validation used in computer programming and data entry that verifies whether every required field in a form or database has been filled out. This check is essential to ensure no critical data is omitted before the data is processed further.

The other options presented do not directly address the student's question about ensuring that values are entered in all critical fields: b. Validity check verifies that the data entered follows certain rules or constraints; c. Reasonableness check confirms that data is logical or reasonable under the circumstances; and d. Field check ensures the data entered into a field is of the correct type or format.

Answer 2

The programmed input validation that ensures a value was entered in all critical fields is: a. Completeness Check.

Step-by-step explanation:

Completeness checks in programmed input validation serve as a gatekeeper for crucial information. When users input data, this validation method ensures that all essential fields within a form, database, or system have received input before moving forward. Its primary goal is to prevent missing or empty values that could disrupt processes or generate errors down the line.

For instance, in an online shopping checkout form, a completeness check ensures that mandatory fields like name, shipping address, and payment details are filled out. If any of these critical fields are left blank, the system would prompt the user to input the necessary information before proceeding.

This validation method is instrumental in maintaining data integrity and accuracy. In sectors like healthcare or finance where precision is paramount, ensuring that all required fields contain data is crucial. It significantly reduces the risk of incomplete records, erroneous calculations, or processing failures due to missing information.

The correct answer is: a. Completeness Check.
