Hi everyone! I'm having problems with using printf("%lld"). I tried %lli, %Ld, %Li and others, but I can't make the following code work - even at my PC, not at the judge:

    long long a = 100000;
    a = a * a;
    printf("%lld", a);

Could anyone please help?

P.S. The only way now is to use cout, which always works fine.
