C, this word is usually pronounced as "C plus plus" in the programmer circle in mainland China, while Western programmers usually pronounce it as "C plus plus" , it is a kind of usage A very broad range of computer programming languages.
#C is a general-purpose programming language with static data type checking that supports multiple programming paradigms. It supports multiple programming styles such as procedural programming, data abstraction, object-oriented programming, and generic programming. (Recommended learning: PHP video tutorial)
CPP is another writing form of the programming language C.
It is the abbreviation of "C Plus Plus". is another computer programming language after C language. C programming language supports all C language syntax at the same time. C is similar to C: but C is a process-oriented programming language, while C is an object-oriented programming language. However, the C language maintains compatibility with the C language, which means that the C language can be inserted into the C program without modification. code.
cpp is the suffix name of source code files written in C language. Its powerful support for classes allows it to write better programs.
C not only has the practical features of efficient computer operation, but is also committed to improving the programming quality of large-scale programs and the problem description capabilities of programming languages.
Language features
Support data encapsulation and data hiding
In C, classes are tools that support data encapsulation, and objects are data encapsulation accomplish. C supports data encapsulation and data hiding by creating user-defined classes.
In object-oriented programming, data and functions that perform legal operations on the data are encapsulated together as a class definition. Objects are declared as variables of a given class. Each object of a given class contains a number of private members, public members and protected members specified by the class. Once a well-defined class is created, it can be viewed as a fully encapsulated entity that can be used as an integral unit. The actual inner workings of a class are hidden, and users of a well-defined class don't need to know how the class works, just how to use it.
Support inheritance and reuse
New types can be declared based on existing C classes. This is the idea of ??inheritance and reuse. Through inheritance and reuse, you can organize the program structure more effectively, clarify the relationships between classes, and make full use of existing classes to complete more complex and in-depth development. The newly defined class is a subclass and becomes a derived class. It can inherit all non-private properties and methods from the parent class as its own members.
Support polymorphism
Use polymorphism to specify performance behavior for each class. Polymorphism forms a tree structure consisting of parent classes and their subclasses. Each subclass in this tree can receive one or more messages with the same name. When a message is received by an object of a class in this tree, the object dynamically determines some usage of the message to be given to objects of subclasses. This feature of polymorphism allows for the use of high-level abstractions.
The combination of inheritance and polymorphism can easily generate a series of similar but unique objects. Due to inheritance, these objects share many similar characteristics. Due to polymorphism, one object can have a unique representation and another object have another representation.

The key to writing a good resume is to clarify the goals, concise structure, and focus the content. First, the resume should be tailored for specific positions, adjust the content according to the position requirements, highlighting the matching skills and experience; second, the structure should be clear, including contact information, personal profile, experience and other modules, and distinguish them with titles and boldness to avoid large paragraphs of text; third, the experience description should be spoken with facts and data, and the verbs should be started with digital quantization and achievement-oriented methods to show actual value; finally, pay attention to the details of the layout, unify the font and spacing, use PDF format, and standardize the name of the file to improve professionalism. Repeated modifications or asking others to check will help improve the quality of your resume.

The core of artificial intelligence is algorithms, especially models that can learn laws from data, such as deep learning. It trains the system through a large amount of data, allowing it to make judgments on new situations, such as face recognition and chatbots. AI is not really intelligent, but statistical methods that mimic human behavior. Common applications include voice recognition (such as Siri), image recognition (such as Alipay face-scanning payment), recommendation systems (such as TikTok and Taobao recommendations), and autonomous driving. AI's capabilities have boundaries, it can only work within the scope of training data, has no real awareness, and relies on a large number of computing resources. When looking at AI, it should be rational. It is an efficient tool but not perfect. It can be used to improve efficiency, but it also needs to be wary of its limitations.

The key to converting PDF to Word is to select the right tool and pay attention to the format preservation. ① Use Adobe Acrobat to directly export to .docx, which is suitable for text-type PDF and is not easy to mess with. The operation steps include opening the file, clicking "Export PDF", selecting the format and downloading and checking; ② Online tools such as Smallpdf and iLovePDF are suitable for daily simple conversion, but you need to pay attention to privacy risks and possible format confusion; ③ New version of Word supports direct import of PDF, which is suitable for situations where only small edits are required. The operation is to insert files and automatically identify content by Word; ④ Scanned files must first use OCR tools to identify text, and pay attention to details such as font changes and misalignment of column tables. It is recommended to manually adjust after conversion to ensure that
