!cin looping errors

qvantry (9)
Alright, so this is about avoiding erros when someone would enter a letter or something that isnt an integer. This work without crashing the program if you were to enter lets say a 'd'. But if I enter multiple nonintegers, lets say 'dddasdwa'. Then the program with loop the error message for as many letters were written. I was wondering if theres any fix for this. Thanks!

  #include <iostream>

using namespace std;

int main()
{
	int integer;

	cout << "Enter an integer: ";
	cin >> integer;
	cin.ignore();

	while (!cin)
	{
		cin.clear();
		cin.ignore();
		cout << "You must enter an integer.\nTry again: ";
		cin >> integer;
		cin.ignore();
	}
	cout << "You entered: " << integer << endl << endl;

	return 0;

@rafae11: I recommend not doing it that way, see my link above for why.
