title: Dev-C++ compile errors
body: <p>I want to use "Dev-C++" for compile c++ codes.
  So I download and install it, and write this code:</p>
  
  <pre><code>#include &lt;iostream.h&gt;
  
  main () {
       cout &lt;&lt; "124";
  }
  </code></pre>
  
  <p>but when I compiled it, it said:</p>
  
  <blockquote>
    <p>In file included from
    E:/Dev-Cpp/include/c++/3.4.2/backward/iostream.h:31,
                     from [myfile path]\Untitled1.cpp:1:
    E:/Dev-Cpp/include/c++/3.4.2/backward/backward_warning.h:32:2:
    warning: #warning This file includes
    at least one deprecated or antiquated
    header. Please consider using one of
    the 32 headers found in section
    17.4.1.2 of the C++ standard. Examples include substituting the  header
    for the  header for C++ includes,
    or  instead of the
    deprecated header . To
    disable this warning use
    -Wno-deprecated.</p>
  </blockquote>
  
  <p>After I saw errors, I change my code to this code:</p>
  
  <pre><code>#include &lt;iostream&gt;
  
  main () {
       cout &lt;&lt; "124";
  }
  </code></pre>
  
  <p>but it said again that errors.</p>
  
  <p>I compile first code easily in Turbo C++, BUT in Dev-C++ ...</p>
  
  <p>What can I do?</p>
