The document provides coding style guidelines for variables, functions, classes and other elements in C++ code. Some of the key points include: - Use meaningful prefixes and names for variables and functions - Initialize variables during declaration when possible - Functions should perform a single well-defined action - Class members should be private with public get/set accessors - Parameter types should be consistent and avoid default values - Loop variables should have meaningful names beyond simple indexes - Prefer clearer alternatives to switch statements in loops - Related functionality should be split across multiple focused functions
