Hi, Hyun-Ho Kyeong,
More information about such undefined behavior~ :)
According to C99 standard:
C99 6.3.1.4 Point 1:
"... If the value of the integral part cannot be represented
by the integer type, the behavior is undefined."
C99 6.5 Point 5:
"... if the result is ... not in the range of representable
values for its type... the behavior is undefined."
