fprintf

fprintf is a standard C library function used for formatted output to files. It writes formatted data to a specified file stream, similar to printf but with the ability to direct output to files rather than just the standard output. It is part of the stdio.h header and is essential for file I/O operations in C programming.

Also known as: fprintf(), file printf, formatted file output, C fprintf, stdio fprintf

🧊Why learn fprintf?

Developers should learn fprintf when working with C or C++ programs that require writing formatted data to files, such as logging, configuration files, or data export. It is particularly useful for creating human-readable file outputs with precise control over formatting, including strings, numbers, and other data types.
