Do not memorize code. Understand the flow of printf : iterating through a string and dispatching to type-specific printers. Understand the state machine of get_next_line : reading, joining, extracting, and cleaning. Understand coordinate geometry for micro_paint : loops inside loops, conditional drawing based on boundaries.
