<li>CDT can infer the header file of a function or class from its use and automatically insert the appropriate
#include directive. For example create a file with a main method and a call to printf. Right click on the call to
printf and select Source &gt; Add Include. CDT will infer that printf is defined in the cstdio header and
automatically insert the #include directive for that header.

<li>CDT can infer the header file of a function or class from its use and automatically insert the appropriate
#include directive. For example create a file with a main method and a call to printf. Right click on the call to
printf and select Source &gt; Add Include. CDT will infer that printf is defined in the cstdio header and
automatically insert the #include directive for that header.

without manual setup.
