How to count number of files in a directory

[flavourofbru]

Hi,

I have a small question.
How do I compute the number of files(which are specific such as .doc) in a directory in C++.

For example, if I have 10 files of type .doc format in a directory, how do I compute this value using C++.

Any help is appreciated.

Thanks!!

I think it depends on OS in which you are working.

If you are on Unix OS then

int i;

i = system(ls -l path/*.doc|wc -l); // here path sholud be complete path
// or path from current directory till the folder where you are
// looking for .doc files.

And in Windows I would imagine it would implement the Win32 API.

For Windows, start here.

I am using Windows.

I have gone through the link given above for windows, but could not understand it properly.

Do we have any other methods for it.

Thanks!!

You call FindFirstFile and then call FindNextFile until is doesnm;t find a file.

If you are looking for all of the files, then find the *.* file.
