ifstream fail isn't cleared?

Hi this is a question regarding how flushing an ifstream works.
I have a text file :
a
1


and execute the following code:
1
2
3
4
5
6
7
8
9
10
 
int i;
    char a;

    ifstream in ("test.txt");
    in >> i;

    if(in.fail())in.clear();
    in >> i;
    if(in.fail()) cout << "Your integer is still invalid!" << endl;
    cout << i << endl;


And regardless of clearing my instream, I still reach a fail state from reading in "1". My question is how reading works with file streams. What should I be doing properly to make the second if condition be false?
