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

Add this line after clearing cin:

std::cin.ignore();

This way, the stream ignores whatever is left on its buffer.
