What does the term “file” mean in the C programming language?

In C language, a file is a data structure used to represent a file. Through the file structure, programs can open, read, write, and close files. In C language, file pointers (FILE*) are commonly used to reference file structures, allowing the use of library functions to operate on files. When performing file operations, it is important to pay attention to the file’s opening mode, read/write position, etc., to ensure proper file manipulation.
