I am in a c++ class and my group is having a hard time making this work... It keeps saying that 'fileOne.open' isn't working. We can't seem to figure out why. Any help would be greatly appreciated. Thank you in advance.

Okay, we've fixed the 'fileOne' problem, but now file four isn't opening... any help is still appreciated. Thank you in advance.

Your code for opening all the files are the same, so I doubt there's any problem there. Did you check to make sure that the string Four actually contains the correct file name?

I can't help but feel there's something wrong with using a loop to read in file names like this.
