Is it safe to print 0 to a file?

Is it safe to print 0 (as unsigned char) into a file? Will that mess up (might the filesystem rely on NULL being file termination? )

I am using a std::ofstream object to write to the file.

It's just an ASCI character and eof() does'nt take 0 as a null character

You can write anything to the file, as long as you don't assign 0 to a pointer/variable in your code.

Yes, you can write 0 to a file. To close it, just close the file handle.

You can write whatever you want to the file, the characters you send are interpreted into the specific character encoding of that file.

Only ofstream:close() will close a file
