When to start here

Fast lookup workflow

  1. Start with cppreference for the general rule, signature, or header.
  2. Check vendor docs when the issue involves implementation notes, platform behavior, or ecosystem-specific guidance.
  3. Return to the handbook when you want the broader teaching context or surrounding tradeoffs.

Example in practice

  1. Pick one resource from this page.
  2. Use it to answer one concrete question about syntax, tooling, or workflow.
  3. Bring the result back into a local example or project build.
