description: Enforce the Euler repository C++ formatting and style rules from AGENTS.md. Use when writing, editing, or reviewing Euler solution code so it matches required includes, types, layout, namespaces, and I/O conventions.

Format Euler Code

Overview

Apply the Euler C++ code-style rules so solutions are consistent, readable, and compliant. Focus on formatting, structure, and required conventions while preserving correctness.

Guidelines

  • •Keep helper functions and structs above main(); keep main() short and focused on orchestration and output.
  • •Use a single translation unit; avoid extra headers unless the problem demands it.
  • •List only required standard headers explicitly; avoid mega-headers.
  • •Qualify all standard library usage with std::; do not use using namespace std;.
  • •Use static_cast<...> for conversions; avoid C-style casts.
  • •Prefer fixed-width integers (std::uint64_t, std::int64_t) and keep constants const or constexpr near use.
  • •Mark file-scope helpers as static (or static inline for small helpers).
  • •Prefer std::vector/std::array; reserve() or pre-size when size is known; use std::size_t for indexing by size.
  • •Use clear loops with early-continue/early-return; avoid unnecessary recursion.
  • •Use std::ios::sync_with_stdio(false); std::cin.tie(nullptr); when reading input.
  • •End final output with std::endl.
  • •Keep comments short and only for non-obvious math or logic; use ASCII only; never reference AGENTS instructions.
  • •Use <primesieve.hpp> for prime generation when needed; use Boost multiprecision only when bounds require it.

Quick Workflow

  1. •Scan the file for style violations: includes, namespaces, helper placement, types, casts, and I/O setup.
  2. •Apply the minimal edits needed to conform to guidelines without changing logic.
  3. •Re-check for unnecessary headers, incorrect types, or missing static helpers.
  4. •Confirm the final output line ends with std::endl.
  5. •Confirm that the program output remains unchanged compared to prior to the code updates.
