title: eclipse cdt auto include <iostream>
body: <p>In Eclipse for Java, library classes are auto-imported in the class file
  and it also prompts to choose which library if 2 library classes have the same method .
  Is there a similar option for Eclipse CDT to automatically include iostream, math.h, stdio.h. Or do I need to type it out for every source file.
  My compiler is Linux GCC.</p>
