stdio.h is a standard C library header file that provides input and output functionality through a set of functions, macros, and types. It enables operations like reading from and writing to files, as well as handling standard input/output streams (stdin, stdout, stderr). This library is fundamental for file handling, console I/O, and formatted data processing in C programming.

Also known as: Standard Input Output Header, stdio, C Standard I/O Library, stdio.h header, Standard I/O
