Which operator yields the remainder after division?

Which operator yields the remainder after division?

• A. MOD - remainder after division
• B. DIV - integer division
• C. Division
• D. Greater than

Answer: (A)

The idea being tested is how to get what’s left over after dividing two numbers, using the modulo operation. The modulo operator returns that remainder directly. For example, when you divide 7 by 3, you can think of it as 7 = 3 × 2 + 1, so the remainder is 1, and 7 mod 3 equals 1. This is why the modulo operator is the best answer: it is designed specifically to produce that leftover value. In contrast, the integer-division operator would give the quotient (2 in this case) without any remainder, plain division would yield a decimal result (2.333…), and a greater-than comparison just checks which number is larger, not performing division at all.
