Why the following c++ code keeps output “bad data, try again”?

Question

int main()
{
        int temp;
        while (cin>>temp, !cin.eof())
        {
                if (cin.bad())
                {
                        throw r         


        

Answer 1

Because x is not an integer, the operator>> operator doesn't read anything, so when you clear the bit and try again, the same thing results.
