Check unnecessary Header file inclusion

[Parag Mahajan]

Hi,

I would like to know if there is any way / tool available by which we
can detect unnecessary header files included in the source files.

Regards,
Parag.

To reduce build times.

Hardly, unless your build system is grossly underspecified.

One reason is to reduce the build time and another one is to actually
make sure we do have only required header inclusions in our source
files.

PC Lint from Gimpel (www.gimpel.com) can do this. It is a commercial
product, not free or open source. I have never actually used it for
this purpose on C++, but I know it works quite well in C.

It does also work on C++,, quite nicely.

Do you have the same opinion on:

- unused variables
- commented out unused code
- not commented out but unreachable code
- duplicated code
- unchecked error return code
- input validation
etc
