Which mathematical operator can generate unexpected results when used with integer numbers?
a) Addition (+)
b) Decrement (--)
c) Modulus (%)
d) Division (/)
e) Multiplication (*)
The answer they want is d) because 10 / 3 produces 3 which some people find unexpected. For me, this is perfectly expected based on knowledge of integer arithmetic. I would tend to answer a), b), and e) because of integer overflow problems. The point is, it's only unexpected if you don't understand. What a strange question.
