It rather simplifies the code. You exit the loop and do whatever is
necessary there.
Testing for the file end is unreliable and non-portable. Many types of
files simply do not support that test. In other cases the test is not
file immutable with the side effects that can change the program logic.
It is well advised to never ever use it.
