HTML5 is the latest HTML standard. Sooner or later, all web programmers will find that they need to use this latest standard. Moreover, many people will feel that it is more difficult to redevelop a website with HTML5 than to develop a website. Migrating from HTML4 to HTML5 is much easier because there are significant differences between the two versions.
In fact, HTML5 does not make any major changes to HTML4. Many of them are similar.
However, there are some important differences you need to know. Listed below are some of the main differences between HTML4 and HTML5 (not all, it is impossible to list them all):
1. The HTML5 standard is still being developed
This first difference is obvious, but so important that I need to start with it. Maybe you've noticed that there's a lot of talk about how cool HTML5 is, but the reality is that HTML5 is an unfinished standard. HTML4 is already 10 years old, but the fact that it is still the current official standard has not changed.
On the other hand, HTML5 is still in its early stages, and future modifications will continue to appear. You must take this into consideration, because the newly added or modified web elements you use on your website will change every year, and you need to constantly update and upgrade your website, which is not what you want. This is why, for now, you're better off using HTML4 in production and only using HTML5 in experiments.
2. Simplified syntax
Simpler doctype declaration is one of the many new features in HTML5. Now you just write and that's it. The syntax of HTML5 is compatible with HTML4 and XHTML1, but not SGML.
3. A new
For Web users, Flash is both a surprise and a pain. There are many web developers who are dissatisfied with the threat HTML5 poses to Flash. But for those of you who put up with bloated Flash videos that took years to load and run, the technology to generate videos with the new

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.

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.

An application that converts XML directly to PDF cannot be found because they are two fundamentally different formats. XML is used to store data, while PDF is used to display documents. To complete the transformation, you can use programming languages and libraries such as Python and ReportLab to parse XML data and generate PDF documents.

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.
