Why Should Inexperienced Programmers Fear Undefined Behavior?

The Enigma of Undefined Behavior for the Inexperienced

Defining undefined behavior is a conundrum that often baffles novice programmers. Consider the precarious act of attempting to free memory allocated with new[] using delete (instead of delete[]). The consequences of such a miscue are as enigmatic as they are dire – anything from an innocuous execution to a catastrophic crash is a potential outcome.

To impart the gravity of undefined behavior to these fledgling coders, a concise explanation that transcends platform-specific idiosyncrasies is essential. The notion of "unreliable" should serve as the cornerstone of your exposition. Software, by its very nature, should strive for reliability. Any behavior that undermines this fundamental principle is inherently undesirable.

Analogous to a treacherous frozen pond, undefined behavior represents a perilous terrain. The fact that someone may have traversed it successfully once provides no assurance of future safe passage. Just as one would hesitate to traverse a frozen pond in uncertain conditions, programmers should refrain from employing code that may harbor undefined behavior.
