This guy doesn't know C very well, either.
First, "scanf" was deprecated over five years ago.
And reopening "stdin" is rarely done, although
it is possible.
Second, there's a buffer overflow. "n" is obtained
from external input, then used to control the "for"

overflow on "a". Also, starting to fill "a" from 1
looks like an error.
Third, the program doesn't actually do anything.
There's no output.
It looks like this approach to C came from
