So what do you do when an index into an array is out of bounds at run-time. You can't perform a check every time because that would go against the C's principle, and at the same time it would degrade performance, making it less useful compared to newer languages.
How would you implement defined behavior without a significant (which is what an if check is at that level) overhead in this case?
