Deprecated Or Antiquated Header

Expand Post »
I'm including these three files in my C++ program:

C++ Syntax (Toggle Plain Text)
  1. #include <stdio.h>
  2. #include <cstdlib>
  3. #include <iostream.h>

The C++ compiler I am using (Dev-C++ 4.9.9.2) Allows me to run this program. but I still receive an error message saying:

C++ Syntax (Toggle Plain Text)
  1. #warning This file includes at least one deprecated or antiquated header. \
  2. Please consider using one of the 32 headers found in section 17.4.1.2 of the \
  3. C++ standard. Examples include substituting the <X> header for the <X.h> \
  4. header for C++ includes, or <iostream> instead of the deprecated header \
  5. <iostream.h>. To disable this warning use -Wno-deprecated.

Why is this happening and how can I stop it? Thanks in advance.

Re: Deprecated Or Antiquated Header
iostream.h is obsolete. use <iostream> instead (notice there is no .h extension).

Re: Deprecated Or Antiquated Header
You can replace all three headers with
#include <iostream>
