cin failure

Code:

---

...
int choice;
cin >> choice;
...

---

if i enter no numerical chars a cin error occurs
that i can't restore with cin.clear()
i detect the error with cin.fail()

is it a fatal error?

TIA

Try something like this one:

Code:

---

#include <iostream>

int main()
{
  int i;
 
  std::cout <<"Enter a number" <<std::endl;
  while (!(std::cin>>i))
  {
    std::cout <<"Again:" <<std::endl;
    std::cin.clear();
    while (std::cin.get() != '\n');
  }

  std::cout <<"You entered " <<i <<std::endl;

}

---

or take out all the std:: and put

Code:

---

using namespace std;

---

at the begining
