I strongly suggest you read the C++ standard (ISO/IEC 14882:1998(E).
The following is a copy of the section D.5:

************************************************************************
D.5 Standard C library headers

For compatibility with the Standard C library, the C++ Standard
library provides the 18 C headers, as shown in Table 100:

Table 100 C Headers

<assert.h> <iso646.h> <setjmp.h> <stdio.h> <wchar.h> <ctype.h>
<limits.h> <signal.h> <stdlib.h> <wctype.h> <errno.h> <locale.h>
<stdarg.h> <string.h>
************************************************************************

To avoid misunderstanding, I also include the note 160:

: The ".h" headers dump all their names into the global namespace,
: whereas the newer forms keep their names in namespace
: std. Therefore, the newer forms are the preferred forms for all uses
: except for C++ programs which are intended to be strictly
: compatible with C.
