Postconditions

Definition

Postconditions are conditions or requirements that must hold true after a certain action or function has been executed. They define what should be expected as a result of running the code.

Analogy

Imagine ordering food at a restaurant. The postcondition would be receiving your meal exactly as you ordered it - hot, delicious, and complete with all the ingredients you requested. If any of these postconditions aren't met, something went wrong in the process.
