Question: How to get file size in C++? Answer: 1. Use the std::ifstream::tellg() member function to get the number of bytes read or written since opening the file stream; 2. Use std::filesystem::directory_iterator to traverse the files in the directory, and Use std::ifstream::tellg() to calculate the number of bytes in each file and add them up to get the total size.

The size of a file is the amount of storage space that a specific file takes up on a specific storage device, such as a hard drive. The size of a file is measured in bytes. In this section, we will discuss how to implement a java program to get the size of a given file in bytes, kilobytes and megabytes. A byte is the smallest unit of digital information. One byte equals eight bits. One kilobyte (KB) = 1,024 bytes, one megabyte (MB) = 1,024KB, one gigabyte (GB) = 1,024MB and one terabyte (TB) = 1,024GB. The size of a file usually depends on the type of file and the amount of data it contains. Taking a text document as an example, the file size may be only a few kilobytes, while a high-resolution image or video file may be

PHP Image Operation: How to Get the Size and File Size of Images In developing websites or applications, we often need to process images. Obtaining the size and file size of images is a common requirement, which can be easily achieved through some functions in PHP. This article will introduce how to use PHP to obtain the size and file size of images, and attach a code example. Get the image size To get the image size, you can use PHP's built-in function getimagesize(). This function will return a file containing the image size

PHP is a server-side scripting language widely used in web development and is designed to provide support for the creation of dynamic web pages. One of the commonly used operations is to get the file size. File size is important to web developers as they need to ensure that the content of their website is not too large to impact the user experience. In PHP, you can use the filesize() function to get the file size. The syntax of this function is as follows: filesize(string$filename):float

How to determine the file size of compressed packages through PHPZipArchive? Summary: PHP's ZipArchive class is a very useful tool that can be used to create, modify and extract compressed archives. However, sometimes we may need to judge the file size in the compressed package so that we can be prepared when dealing with large files. In this article, we will learn how to determine the size of the files in the compressed package through PHP's ZipArchive class. Steps: First, we need to create a Z

There are three ways to efficiently obtain file size in Python: 1. Use os.path.getsize(), which is suitable for a single file, and error handling is required; 2. Use pathlib.Path.stat().st_size to provide an object-oriented interface, which is suitable for a single file; 3. Use os.scandir() combined with os.path.getsize(), which is suitable for batch processing of files to improve performance.

To reduce the size of HTML files, you need to clean up redundant code, compress content, and optimize structure. 1. Delete unused tags, comments and extra blanks to reduce volume; 2. Move inline CSS and JavaScript to external files and merge multiple scripts or style blocks; 3. Simplify label syntax without affecting parsing, such as omitting optional closed tags or using short attributes; 4. After cleaning, enable server-side compression technologies such as Gzip or Brotli to further reduce the transmission volume. These steps can significantly improve page loading performance without sacrificing functionality.
