First,
pow(x, y)
on GNU C++ 4.7 compiler calculates something like with help of Taylor series. It is not 100% accurate, for example,pow(5, 2)
may return something like25.0000000000001
or24.9999999999999
. So you can write your own function that calculates xy for integer x and y, or you can useround
function. Also some C++ compilers provide overloadpow(double, long long)
, which will work as intended, because it is binary exponentiation and double type stores integers less than 253 without errors.Second, you declare
d
asint
, but 104·815 + 104 > 109, so overflow will happen.And third, you don't check, whether d < 109.
