How do you write a while loop or a for loop that ONLY takes positive intergers? the interger has to be greater than or equal to 3.

This is what I had until I realized if I enter anything thats not a number it goes into an infinite loop.

int input;

cout << "Enter an integer : ";

cin >> input;

while (n < 3) //while number < 3, ask to re-enter

{

cout << endl;

cout << "Integer must be >=3 . Try again ";

cin>>input;

}
