Open for Features, Closed for Drama – The OCP Quiz

Why break something that’s working when you can extend it like adding toppings on a pizza? 🍕 👨‍🏫 **Definition:** The Open/Closed Principle (OCP) says: *Software entities like classes, modules, functions should be open for extension, but closed for modification.* Translation? You should be able to add new stuff without poking or rewriting old stuff — because touching old code is how bugs throw parties. 🎉🐛 🛠️ **Real-Life Examples:** - A **music player** lets you add new songs but doesn’t ask you to open the circuit board. - A **burger joint** that allows extra toppings without rebuilding the whole kitchen. - A **phone case** that fits new models without re-sculpting your entire phone. 🎯 In this quiz, you’ll: - Refactor rigid code into flexible beauty using polymorphism - Detect violations of OCP and rescue classes from modification madness - Write code that grows like LEGO, not Jenga If you’ve ever broken 5 tests while adding one feature, this quiz is for you. Time to become the Feature Whisperer! 🧙‍♂️📦
