Code structure refers to the organization and arrangement of code within a program. It involves how different components, such as functions, classes, and modules, are laid out to ensure clarity and maintainability. A well-structured codebase makes it easier for developers to read, understand, and modify the code, which is essential for collaboration and long-term project success. Good code structure often follows specific principles, such as DRY (Don't Repeat Yourself) and KISS (Keep It Simple, Stupid). These principles help reduce redundancy and complexity, making the code more efficient and less prone to errors. Adopting a consistent coding style and using meaningful names for variables and functions also contribute to a better code structure.
