What is the recommended formatting style for C++?
There is no one-size-fits-all answer to this question as the recommended formatting style for C++ can vary depending on the context. However, there are several widely accepted formatting styles for C++ that are used in various communities and organizations. Some of these include:

The Google C++ Style Guide: This is a widely used guide that provides a set of rules and guidelines for writing C++ code that is consistent and readable. The guide covers a range of topics, including indentation, line length, naming conventions, and more.

The LLVM Coding Standards: The LLVM project, a collection of modular and reusable compiler and toolchain technologies, has its own set of coding standards for C++. These standards are similar to the Google C++ Style Guide in many ways, but also have some unique rules and recommendations.

The ISO C++ Standard: The ISO C++ Standard provides a set of guidelines and recommendations for writing C++ code that is portable and conforms to the latest version of the C++ language standard.

Ultimately, the choice of formatting style will depend on the preferences of the individual or organization, and the specific requirements of the project. However, it's important to choose a consistent style and stick to it throughout the development process, as this can greatly improve the readability and maintainability of the code.
