<cstdio>

The <cstdio> header is a wrapper for the C standard <stdio.h> header, which declares input and output types, macros, and functions. See also <cwchar> for wide character I/O functions.

C++ I/O streams offer more flexibility, type-safety, and clarity. On the other hand, C I/O offers simplicity and compatibility with C libraries. See Chapter 9 for an overview of the C++ I/O stream classes.
