Code Review

This pull request adds four new documentation files covering core C++ OOP concepts: attributes, constructors, methods, and access modifiers. The review feedback highlights several critical issues across all files, including improperly escaped markdown front matter that will break Docusaurus parsing, and code blocks containing escaped characters and HTML entities. Additionally, the reviewer noted C++ code quality issues such as an uninitialized member variable in attributes.md, a missing <string> header in constructors.md, and a lack of const-correctness in methods.md.

Important

The consumer version of Gemini Code Assist on GitHub is being sunset. Starting June 18, 2026, new organization installations will be blocked, and all code review activity will officially cease on July 17, 2026.

You need to update or rewrite your code because the entire documentation does not meet our expectations.
