10 Techniques to Understand Code You Don’t Know
summary
Ten concrete techniques to make unknown C++ (or other) code comprehensible with examples and tools: follow the UI or I/O framework to a specific function via the purple wormhole, pick a small mastered stronghold and expand from it, inspect representative call stacks and flame graphs, then speed-read by starting from outputs, using word-count/span analysis (tool: fluency.pp.com/word-counts), filtering control flow, and scanning for the main action. For deep work, decouple and rename (showing total_price → price_after_taxes), practice on isolated functions, and pair up; these steps reportedly save hundreds of hours.
