title: compiling a #include <cstdlib> in Xcode - error during compilation: file not found
body: <p>I have added one framework in my project, where to get the callbacks of framework I need to implement c++ code,for which I have added c++ classes which are .mm from .cpp </p>
  
  <p><a href="https://stackoverflow.com/questions/534861/compiling-a-c-class-in-xcode-error-during-compilation-stl-vector">as per suggestions given in this link</a></p>
  
  <p>I also came across few posts of StackOverflow, where I found either I have to go for C++ or Objective C source type(as suggestion of few members).</p>
  
  <p>I am looking to compile c++ code along with Objective C classes,but I am getting file not found error (compile time) for <code>#include &lt;cstdlib&gt; and #include &lt;string&gt;</code> </p>
  
  <p>Please let me know any one worked around it.or faced same Issue.</p>
  
  <p>Thanks In Advance!!! </p>
