You are looking for cin.fail();

int input;

cin >> input;

while (cin.fail())
{
cout << "End of file or data type mismatch occured. Try again: ";
cin >> input;
}

You might want to flush the stream before grabbing anything else. You might not have to but I always do.

cin.ignore(256, '\n');

You can also just say

if (//name of stream)

to check if it's good. It will return true if the stream is still good. There are several stream flags but most of them aren't really necessary.
