hello rooters,
I am using while(!feof(file)){ process file } in my code so that if there are files missing in my folder, the loop will not terminate until all files are read, I have .dat fles in my folder I am reading files from. Anyone, who can help me.
thanks,

Hi Towseef,
this does not seem to be related to ROOT?
See e.g. here for example code that reads lines from a text file in C++.

Hope this helps!

Hey Enrico,
I basically loop over the files in my folder, the file name is auau.0000.dat and goes up to auau.04999.dat, there are some files missing in between, I want to skip those files and continue.
thanks, Enrico

See the example code I linked, the line that checks whether the file was opened correctly is if(!file).

Note that as this is a pure C++ question you will find a lot of tutorials and explanations on the web.

Cheers,
Enrico
