Four Simple Ways to Draw a Rectangle in HTML
Article Introduction：This article will introduce four basic ways to draw shapes on web pages: using HTML and CSS, using CSS only, using SVG, and using HTML canvas elements.
Key Points
The four basic ways to draw shapes on web pages are: using HTML and CSS, using only CSS, using SVG, and using HTML canvas elements.
HTML and CSS can be used to create simple shapes such as rectangles and circles, while using CSS alone can create shapes through pseudo-elements such as ::before or ::after. SVG allows creating more complex shapes, while HTML canvas elements can be used to create graphical and interactive features.

How to use virtual functions in C?
Article Introduction：To implement polymorphism using virtual functions in C, you need to declare the function as virtual in the base class and override in the derived class. 1. Declare virtual functions in the base class, such as draw() of the Shape class. 2. Rewrite virtual functions in derived classes, such as draw() of Circle and Rectangle classes. 3. Use virtual destructors to ensure safe deletion of objects. 4. Use override keyword appropriately to avoid errors. 5. Consider pure virtual functions to design interfaces. 6. Pay attention to virtual function analysis in multiple inheritance. The rational use of virtual functions can enable flexible and scalable code, but requires trade-offs on performance overhead and complexity.

Pure Virtual Functions in C
Article Introduction：Pure virtual functions are the key mechanisms used in C to define abstract classes and interfaces, and their core role is to force derived classes to implement specific methods. 1. The pure virtual function is declared through virtualvoidfunc()=0; and the implementation is not provided, making the class an abstract class and cannot be instantiated; 2. It is used to simulate the interface to ensure that the subclass must rewrite the method, such as the draw() of the Shape base class in the graphics library; 3. Supports runtime polymorphism, allowing the base class pointer to call the implementation of different subclasses; 4. Although the abstract class cannot create objects, it can contain constructors, member variables and implemented ordinary functions; 5. If the derived class does not fully implement all pure virtual functions, it will also become an abstract class; 6. In special cases, the pure virtual function can provide default implementation for derivation.

What is an abstract class in C ?
Article Introduction：The key to an abstract class is that it contains at least one pure virtual function. When a pure virtual function is declared in the class (such as virtualvoiddoSomething()=0;), the class becomes an abstract class and cannot directly instantiate the object, but polymorphism can be realized through pointers or references; if the derived class does not implement all pure virtual functions, it will also remain an abstract class. Abstract classes are often used to define interfaces or shared behaviors, such as designing Shape classes in drawing applications and implementing the draw() method by derived classes such as Circle and Rectangle. Scenarios using abstract classes include: designing base classes that should not be instantiated directly, forcing multiple related classes to follow a unified interface, providing default behavior, and requiring subclasses to supplement details. In addition, C
