How Are Indefinite Loops Used for Validating Data? Why Is

Question

Examlex · Accepted Answer

The Answer is Programmers commonly use indefinite loops when validating input data. Validating data is  the process of ensuring that a value falls within a specified range. For example, suppose you  require a user to enter a value no greater than 3. If the user enters 3 or less at the first prompt, the loop never executes. However, if the user enters a number greater than 3, the shaded loop executes, providing the user with another chance to enter a correct value. While the user continues to enter incorrect data, the loop repeats. Novice programmers often make the mistake of checking for invalid data using a decision instead of a loop. That is, they ask whether the data is invalid using an if statement; if the data is invalid, they reprompt the user. However, they forget that a user might enter incorrect data multiple times. Usually, a loop is the best structure to use when validating input data.
