Learn more about the difference between front-end and back-end
Front-end and back-end are two very important concepts in software development. They are responsible for different functions and tasks. In the Internet age, the distinction between front-end and back-end has become very obvious, and a deep understanding of their differences is very important for people who want to engage in software development.
Front-end, as the name suggests, is the front-end part of the software, also called the client. It is an interface that directly interacts with users, including web page layout, design, interactive operations, content display, etc. Front-end engineers are mainly responsible for converting UI/UX designs provided by designers into implementable web pages or applications, so that users can interact with the system through the interface. In front-end development, commonly used technologies include HTML, CSS, JavaScript, etc., which are the basis for building web pages and mobile applications.
The opposite of the front end is the back end, also called the server side. The backend is the part responsible for processing data storage, logical operations, business rules, etc. Its interface for direct interaction with users is relatively more abstract and hidden. Back-end engineers are mainly responsible for designing and developing applications that interact with the database to ensure that the system can run efficiently and safely. In back-end development, commonly used technologies include Java, Python, C#, Ruby, etc., which are usually used to write server-side logic code.
The difference between the front-end and the back-end is mainly reflected in the following aspects:
- User interaction: The front-end is responsible for the design and interactive operation of the user interface, while the back-end is responsible for processing users The passed data is processed with corresponding business logic.
- Technology stack: The front-end mainly uses technologies such as HTML, CSS, and JavaScript, and the back-end mainly uses technologies such as Java, Python, and C#. Each technology has its own characteristics and applicable scenarios.
- Development direction: The front-end mainly focuses on user experience and interface design, and the development direction includes Web development, mobile application development, etc.; the back-end mainly focuses on system architecture and performance optimization, and the development direction includes large-scale system development, cloud computing, etc.
- Cooperation method: In actual software development projects, the front-end and back-end usually need to work closely to complete a complete application. The front-end is responsible for page presentation and interaction, and the back-end provides data processing and business logic support.
In general, the front-end and back-end perform their respective duties in software development, and only by working together can a stable and efficient system be built. An in-depth understanding of the differences between front-end and back-end can help developers better choose their own development direction, improve their professional capabilities, and better coordinate front-end and back-end work in team collaboration.

In C language, the main difference between char and wchar_t is character encoding: char uses ASCII or extends ASCII, wchar_t uses Unicode; char takes up 1-2 bytes, wchar_t takes up 2-4 bytes; char is suitable for English text, wchar_t is suitable for multilingual text; char is widely supported, wchar_t depends on whether the compiler and operating system support Unicode; char is limited in character range, wchar_t has a larger character range, and special functions are used for arithmetic operations.

The difference between multithreading and asynchronous is that multithreading executes multiple threads at the same time, while asynchronously performs operations without blocking the current thread. Multithreading is used for compute-intensive tasks, while asynchronously is used for user interaction. The advantage of multi-threading is to improve computing performance, while the advantage of asynchronous is to not block UI threads. Choosing multithreading or asynchronous depends on the nature of the task: Computation-intensive tasks use multithreading, tasks that interact with external resources and need to keep UI responsiveness use asynchronous.

There is no built-in sum function in C language, so it needs to be written by yourself. Sum can be achieved by traversing the array and accumulating elements: Loop version: Sum is calculated using for loop and array length. Pointer version: Use pointers to point to array elements, and efficient summing is achieved through self-increment pointers. Dynamically allocate array version: Dynamically allocate arrays and manage memory yourself, ensuring that allocated memory is freed to prevent memory leaks.

C language functions are the basis for code modularization and program building. They consist of declarations (function headers) and definitions (function bodies). C language uses values to pass parameters by default, but external variables can also be modified using address pass. Functions can have or have no return value, and the return value type must be consistent with the declaration. Function naming should be clear and easy to understand, using camel or underscore nomenclature. Follow the single responsibility principle and keep the function simplicity to improve maintainability and readability.

char and unsigned char are two data types that store character data. The main difference is the way to deal with negative and positive numbers: value range: char signed (-128 to 127), and unsigned char unsigned (0 to 255). Negative number processing: char can store negative numbers, unsigned char cannot. Bit mode: char The highest bit represents the symbol, unsigned char Unsigned bit. Arithmetic operations: char and unsigned char are signed and unsigned types, and their arithmetic operations are different. Compatibility: char and unsigned char

H5. The main difference between mini programs and APP is: technical architecture: H5 is based on web technology, and mini programs and APP are independent applications. Experience and functions: H5 is light and easy to use, with limited functions; mini programs are lightweight and have good interactiveness; APPs are powerful and have smooth experience. Compatibility: H5 is cross-platform compatible, applets and APPs are restricted by the platform. Development cost: H5 has low development cost, medium mini programs, and highest APP. Applicable scenarios: H5 is suitable for information display, applets are suitable for lightweight applications, and APPs are suitable for complex functions.

Although C and C# have similarities, they are completely different: C is a process-oriented, manual memory management, and platform-dependent language used for system programming; C# is an object-oriented, garbage collection, and platform-independent language used for desktop, web application and game development.
