C++ is a widely-used programming language known for its power and performance. When writing code in C++, following a consistent style guide can greatly improve code readability and maintainability. While there are several style guides available, let’s explore two popular ones apart from the well-known Google C++ Style Guide.
1. LLVM Coding Standards
The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Their coding standards provide detailed guidelines for writing code in C++ and other languages. The LLVM coding standards emphasize clarity, performance, and maintainability.
Some notable features of the LLVM style guide include:
- Naming Conventions: The guide provides conventions for variable names, function names, and class names. It also covers naming conventions for constants and enumerators, among others.
- Formatting: The guide covers indentation, line length, whitespace usage, and other formatting rules to make the code more readable.
- Language Features: It provides recommendations for using C++ language features, including exceptions, templates, and lambdas.
- Documentation: The guide encourages the use of Doxygen-style comments for documenting code.

2. Microsoft C++ Core Guidelines
Microsoft’s C++ Core Guidelines, developed by renowned C++ experts, provide a comprehensive set of guidelines for writing modern and safe C++ code. These guidelines are aimed at enhancing code maintainability, correctness, and performance.
Key highlights of the Microsoft C++ Core Guidelines include:
- Type Safety: The guidelines focus on using strong and static typing to avoid errors and improve compiler optimizations.
- Memory Management: Recommendations for smart pointer usage, rule-of-zero, and avoiding manual memory management.
- Concurrency: Guidelines for writing safe and efficient concurrent code, including proper usage of synchronization primitives and avoiding race conditions.
- Error Handling: Best practices for handling errors, including the use of exceptions, error codes, and providing clear diagnostics.
- Container Usage: Guidelines for using C++ standard library containers and algorithms effectively.

Summary
While the Google C++ Style Guide is widely known and used, it’s important to acknowledge other popular style guides like the LLVM Coding Standards and Microsoft C++ Core Guidelines. Each of these style guides has its own strengths and focuses on different aspects of code quality. By following a consistent and well-established style guide, developers can write clean, readable, and maintainable C++ code.
