cpp - Contest C++ Reference
Role
cp4cpp.com/cpp is the Contest C++ Reference.
It exists for quick, correct, readable lookup of C++ syntax, STL, idioms, and contest-relevant language behavior.

Purpose
- Look up syntax, idioms, and STL use cases quickly and reliably.
- Notice typical features and common mistakes in
C++11,C++14,C++17, andC++20. - Keep contest-useful C++ knowledge filtered, version-aware, and easier to digest.

Learning Style
Root-like learning: users learn foundational prerequisite material in any order, as shared primitives used by other navigations.
Strengths To Preserve
- C++ lookups help learners who are unfamiliar with syntax, structure, idioms, and standard library features.
- Contest learners need fast STL, syntax, and idiom reminders.
- Advanced learners still need completeness checks and version-specific reminders.
Weaknesses To Fix
- Common STL traps stay scattered across blogs, notes, and editorials.
- Version changes matter, but explanations are often split across unrelated sources.
CP4CPP Rules
- Keep
cppfiltered, version-aware, and focused on contest use. - Group duplicated pages by use case and characteristic when that improves lookup.
- Only separate contest-relevant options for
C++11,C++14,C++17, andC++20. - Prefer verified standard documentation and clearly cited first-hand references.
