Use a token iterator.

Wow, you guys are so helpful. No wonder nobody talks about programming here.

Nobody talks about programming because we don't have to. We already know everything and you're just retarded.

You must be new here so let me be the first to welcome you to the world of internet.

But FFS if you want help an ad hominem won't convince anyone to do so.

PS. Look for a "Completely reusable tokenizer" from "Thinking in C++ vol.2".

Would you walk into a literature club meeting and ask how to find the subject of a sentence? Please don't disturb our gentlemanly pursuits with your commoner ramblings, we are busy drinking tea and reading SICP. (While wearing our fezzes and monocles.)

Try something like so:

do {
   if (!cin) {
      cin.flush();
      cin.clear();
   }
   cint >> integer;
} while (!cin);

Why not? They should then show the fuckin idiot why it is the literature club.

Version .9:

char shitbuf [1024];
int integer

do {
   if (cin.fail()) {
      cin.getline(shitbuf, 1024, '\n');
      cin.clear();
   }
   cin >> integer;
} while (cin.fail());

def IntInput():

    while True:

        try:

            yield int(raw_input())

        except ValueError:

            pass

        except EOFError:

            raise StopIteration
