In VSCode, you can quickly switch the panel and editing area through shortcut keys. To jump to the left Explorer panel, use Ctrl Shift E (Windows/Linux) or Cmd Shift E (Mac); return to the editing area to use Ctrl ` or Esc or Ctrl 1~9. Compared to mouse operation, keyboard shortcuts are more efficient and do not interrupt the encoding rhythm. Other tips include: Ctrl KCtrl E Focus Search Box, F2 Rename File, Delete File, Enter Open File, Arrow Key Expand/Collapse Folder.

Use the seekg and tellg methods of std::ifstream to obtain file size across platforms. By opening a binary file and positioning it to the end, use tellg() to return the number of bytes; 2. It is recommended to use std::filesystem::file_size for C 17 and above. The code is concise and errors are handled through exceptions. The C 17 standard must be enabled; 3. On POSIX systems, the stat() function can be used to efficiently obtain file size, which is suitable for performance-sensitive scenarios. The appropriate method should be selected based on the compiler and platform, and std::filesystem should be used first (if available), otherwise use ifstream to ensure compatibility, or use st on Unix systems

When opening the software or game, a prompt suddenly appears that "the application cannot start normally (0xc0000906)" appears, and many users will be confused and don't know where to start. In fact, most of these errors are caused by corruption of system files or missing runtime libraries. Don't rush to reinstall the system. This article provides you with several simple and effective solutions to help you quickly restore the program to run. 1. What is the error of 0xc0000906? Error code 0xc0000906 is a common startup exception in Windows systems, which usually means that the program cannot load the necessary system components or running environment when running. This problem often occurs when running large software or games. The main reasons may include: the necessary runtime library is not installed or damaged. The software installation package is endless

memory_order_relaxed is suitable for scenarios where only atomicity is required without synchronization or order guarantee, such as counters, statistics, etc. 1. When using memory_order_relaxed, operations can be rearranged by the compiler or CPU as long as the single-threaded data dependency is not destroyed. 2. In the example, multiple threads increment the atomic counter, because they only care about the final value and the operation is consistent, the relaxed memory order is safe and efficient. 3. Fetch_add and load do not provide synchronization or sequential constraints when using relaxed. 4. In the error example, the producer-consumer synchronization is implemented using relaxed, which may cause the consumer to read unupdated data values because there is no order guarantee. 5. The correct way is

The use of NumPy arrays includes: 1. Creating arrays (such as creating from lists, all zeros, all ones, and ranges); 2. Shape operations (reshape, transpose); 3. Vectorization operations (addition, subtraction, multiplication and division, broadcast, mathematical functions); 4. Indexing and slicing (one-dimensional and two-dimensional operations); 5. Statistical calculations (maximum, minimum, mean, standard deviation, summing and axial operations); these operations are efficient and do not require loops, and are suitable for large-scale numerical calculations. Finally, you need to practice more.

When using the argparse module, the parameters that must be provided can be achieved by setting required=True. 1. Use required=True to set optional parameters (such as --input) to be required. If not provided when running the script, an error will be reported; 2. Position parameters are required by default, and there is no need to set required=True; 3. It is recommended to use position parameters for necessary parameters. Occasionally, the optional parameters of required=True are used to maintain flexibility; 4. required=True is the most direct way to control parameters. After use, the user must provide corresponding parameters when calling the script, otherwise the program will prompt an error and exit.
