Question

(True/False) The process of input validation works as follows: when the user of a program enters invalid data, the program should ask the user “Are you sure you meant to enter that?” If the user answers “yes,” the program should accept the data.

Answer

FALSE.

Explanation:

  • Most of the time, input validation doesn't involve asking the user if they're sure they're not entering incorrect data and then accepting it if they say "yes."
  • Input approval is centered around guaranteeing that the entered information meets explicit standards or imperatives, and in the event that it doesn't, suitable moves are made to deal with the invalid info.
  • When a user enters incorrect data during input validation, the program typically provides feedback or prompts the user to correct their input. Error messages, highlighting the incorrect input, or asking the user to re-enter the data until valid input is provided are all examples of this.
  • Accepting invalid data without appropriate validation goes against the goal of input validation, which is to ensure that the data being entered is correct and true.

Hence, the given statement is False.
