Article Introduction：Event-driven programming in C++: Improving code maintainability and readability In C++, event-driven programming (EDP) provides a way to manage events and responses in an application, which helps improve code maintainability performance and readability. EDP ​​Principle The core principle of EDP is to decompose application logic into independent components, each component is responsible for processing specific event types. The application monitors system events (such as button clicks or keyboard input) and calls the appropriate event handler function when the event occurs. Benefits Using EDP has the following benefits: Higher maintainability: Event handlers are independent of the main application logic, making them easier to maintain and update. Greater readability: EDP makes code more modular and structured

Article Introduction：There are two main techniques for achieving real-time interactivity in C++ graphics programming: Event handling: using libraries (such as SFML) to detect and respond to user input, such as mouse movements and keyboard presses. Loops: Continuously execute a block of code, updating game state, drawing graphics, and processing input until certain conditions are met. Practical case: Snake game: Use SFML for event processing, and achieve real-time interactivity of the Snake game by looping to update the snake's body position, checking collisions and drawing graphics.
