   fscanf (STDIN, "%d", &a);
the program goes beserk as soon as the first non-number is read out of standard input.

in both cases, you need error checking (which you "know about").

No actual C programmer who has been around the block more than halfway should do that. The mantra is: "read into a character buffer, then parse that".

It's more code, sure, but it buys you a lot of good things. I/O is hard.

No C++ programmer who has been around the block more than halfway should do

    cin >> a;
and assume that it works.

But also ...

    sscanf (the_buffer, "%d", &a);
doesn't help the problem in any substantive way.
