Day 16: Exceptions - String to Integer

Objective
Today, we're getting started with Exceptions by learning how to parse an integer from a string and print a custom error message. Check out the Tutorial tab for learning materials and an instructional video!

Task
Read a string, , and print its integer value; if cannot be converted to an integer, print Bad String.

Explanation

Sample Case contains an integer, so it should not raise an exception when we attempt to convert it to an integer. Thus, we print the .
Sample Case does not contain any integers, so an attempt to convert it to an integer will raise an exception. Thus, our exception handler prints Bad String.
