title: deleting a file with string in the arguments
body: <p>How can i remove a file from the directory in <code>c++</code> ?</p>
  
  <p>I know this function <code>int remove ( const char * filename )</code> deletes the file whose file name is specified in the argument. But it accepts only <code>char*</code> . Is there any other function in c++ that accepts <code>string</code> as it's argument ?</p>
