Back to Basics: Design Patterns
summary
Fixes a screensaver bug by replacing hardcoded spawn bounds (300×300) with a singleton configuration manager implemented via a C++11 static-local instance so one source of window width/height exists; wraps a third‑party Text class with an object adapter that forces uppercase green text without changing the original library; replaces fixed for loops (100 pushes) with STL-style iterators and scales to 1,000 circles rendered with SFML. Notes thread‑safety and copy‑semantics caveats and tradeoffs for each pattern.
