Description: File reading is the process of accessing and retrieving data from a file stored in a file system. This process is fundamental in programming and data handling, as it allows programs to interact with persistent information. In various programming languages, file reading is performed using specific functions and commands that facilitate opening, reading, and closing files. The ability to read files is essential for various applications, from data manipulation to system configuration, enabling developers and system administrators to access critical information efficiently. File reading can involve different formats, such as plain text, CSV, JSON, among others, adding versatility to its use. Additionally, the way reading is performed can vary, allowing for reading the entire file, line by line, or in blocks, depending on the program’s needs and the file size. This process is not only crucial for data retrieval but also a key component in file writing, where data can be modified and saved back to the system.
