Code Maintenance & Programming Rules

 This guide outlines essential best practices spanning code style, architectural design, debugging, testing, performance, and portability—all aimed at reducing the long-term cognitive load of code maintenance. 🎨 1. Style Code is written for humans to read, and only incidentally for computers to execute. Variable Naming : Use descriptive names for global variables, and short names for local variables. Precision and Consistency : Use active names for functions (e.g., calculateTotal ). Above all, keep your coding style consistent throughout the project. Structure & Expressions : Use a consistent indentation and brace ( {} ) style to show program structure visually. Use the natural form for expressions. Use parentheses to make the semantics unambiguous. Break up overly complex expressions to keep them clear. Side Effects & Macros : Beware of functions with side effects. Avoid function-like macros; if unavoidable, parenthesize the macro body and arguments carefully. Magic Numbe...
