fstream Input/output stream class to operate on files. Objects of this class maintain a filebuf object as their internal stream buffer , which performs input/output operations on the file they are associated with (if any).

The fstream class (short for "file stream") is used to read and write into files. The fstream class is defined in the <fstream> header file. To open a file, pass the file path into the constructor: The fstream class has a variety of functions for reading and writing files which are listed below.

The <fstream> library provides classes for reading and writing into files or data streams. A list of useful fstream classes can be found in the table below. Learn more about files in our C++ Files Tutorial.

basic_fstream: The class template describes an object that controls insertion and extraction of elements and encoded objects using a stream buffer of class basic_filebuf<Elem, Tr>, with elements of type Elem, whose character traits are determined by the class Tr. basic_ifstream

2025年1月11日 · File handling in C++ involves steps such as naming, opening, writing, reading, and closing files, utilizing classes like ifstream, ofstream, and fstream for efficient data storage and retrieval.

2023年8月4日 · The class template basic_fstream implements high-level input/output operations on file based streams. It interfaces a file-based streambuffer (std::basic_filebuf) with the high-level interface of (std::basic_iostream).

There are three classes included in the fstream library, which are used to create, write or read files: To create a file, use either the ofstream or fstream class, and specify the name of the file. To write to the file, use the insertion operator (<<). MyFile << "Files can be tricky, but it is fun enough!"; Why do we close the file?

C++ Library - <fstream> - This data type represents the file stream generally, and has the capabilities of both ofstream and ifstream which means it can create files, write information to files, and read information from files.
