How do you clear the input buffer?

Code:

int i = 0;
std::cout << "Enter an integer ";
std::cin >> i;

For example the code above and the user enter a char instead of an integer.

Anyway I already tried fflush (stdin) and std::cout << flush and it doesn't work

either.

EDIT:

Never mind I got it to work now.

Code:

int ch;

cin.clear();
while ((ch = std::cin.get()) != '\n' && ch != EOF);

Title: All in a day's work.

If fflush doesn't work, you're SOL.

Try avoid using the lame C++ iostream, if you can. It's really garbage.

I only used fflush because of the results that were presented to me by Google.

Yes I will try to avoid using C++ iostream from now on.
