Which of the following is the MOST likely situation tha…

A web developer is responsible for a simple web application that books holiday accommodations. The frontfacing web server offers an HTML form, which asks for a user’s age. This input gets placed into a signed
integer variable and is then checked to ensure that the user is in the adult age range.
Users have reported that the website is not functioning correctly. The web developer has inspected log files and
sees that a very large number (in the billions) was submitted just before the issue started occurring. Which of
the following is the MOST likely situation that has occurred?

A.
The age variable stored the large number and filled up disk space which stopped the application from
continuing to function. Improper error handling prevented the application from recovering.

B.
The age variable has had an integer overflow and was assigned a very small negative number which led to
unpredictable application behavior. Improper error handling prevented the application from recovering.

C.
Computers are able to store numbers well above “billions” in size. Therefore, the website issues are not
related to the large number being input.

D.
The application has crashed because a very large integer has lead to a “divide by zero”.
Improper error handling prevented the application from recovering.
