A class in C is a data type used to encapsulate data and define behavior. Its characteristics include: encapsulation: encapsulating data and behavior in a single unit; inheritance: allowing classes to inherit properties and behavior from other classes Method; Polymorphism: Allows objects to behave differently depending on their type.
Classes in C
In C, a class is a data type used to store data and Define behavior. It is similar to a real-world object and contains data about the object (called member variables) and operations for interacting with the object (called member functions).
Main features of classes
Class structure
The typical structure of a class is as follows:
<code class="cpp">class ClassName { private: // 私有成员变量和函数 protected: // 受保护的成员变量和函数 public: // 公共成员变量和函数 };</code>
Using Classes
To use a class, you need to define an object:
<code class="cpp">ClassName objectName;</code>
You can then access it via the access operator (. `) Access the members of this object:
<code class="cpp">objectName.memberVariable; objectName.memberFunction();</code>
Benefits of Classes
Using classes can bring many benefits to your program, including:
