ofstream

ofstream is a C++ standard library class for output file stream operations, part of the <fstream> header. It provides an interface to write data to files on disk, supporting formatted and unformatted output operations. It inherits from ostream, enabling use of stream insertion operators (<<) and other output methods.

Also known as: output file stream, fstream output, C++ file output, ostream to file, file output stream

Why learn ofstream?

Developers should learn ofstream when working with C++ applications that require persistent data storage, such as logging systems, configuration file generation, or data export features. It is essential for tasks like saving user data, creating reports, or writing binary files, offering a type-safe and efficient way to handle file output compared to low-level C file I/O functions.
