WebNov 3, 2014 · That leaves us with cin.rdstate() which is true if the eofbit or badbit or failbit is asserted. However, there's a more idiomatic C++ way to express almost that same thing: while (!(cin >> number)) This relies on the operator bool member function which returns false if either failbit or badbit are set. In a real program, I think I would want ...

You should check for errors by calling cin.good(), and try to clear them with cin.clear(), but you shouldn't try to clear some errors (like EOF) and instead should quit on them.
