Final answer:
The statement is true, the feof function returns a non-zero value (commonly one) after an attempt to read past the end of a file has been made.
Step-by-step explanation:
The student's question is about the behavior of the feof function in a programming context. The feof function indeed returns a non-zero value (which is often one) when the end of a file is reached during reading. The exact value returned can depend on the implementation, but for the purposes of checking for the end of file, any non-zero value is treated as true.
It's important to note that feof only returns true after an attempt is made to read past the end of the file. So if you are reading a file and reach the end, feof won't return true until you try to read again, which will fail because you are already at the end of the file.
