std::cin.clear() fails to restore input stream in a good state

Question

In order to test bool i/o, I tried to run this short program:

#include 

int main()
{
 while(true)
 {
  bool f;
  if (std::cin >> f)
   std         


        

Answer 1

Try to use following combo:

cin.ignore(INT_MAX, '\n'); // ignore all characters in the current line

cin.clear(); // restore 'good' flag

Using only cin.ignore() will discard only one character in the buffer.
