Which statement about integer division in C is true?

• A. The result is truncated toward zero.
• B. The result is a floating-point value.
• C. Division by zero returns NaN.
• D. Division only works for positive numbers.

Answer: (A)

In C, dividing two integers yields an integer result by discarding the fractional part, i.e., truncating toward zero. This means positive quotients are rounded down toward zero (7/3 becomes 2), and when negatives are involved the fraction is simply dropped toward zero (-7/3 becomes -2, 7/-3 becomes -2, -7/-3 becomes 2). The result remains an integer type, not a floating-point value, unless you explicitly cast the result. Division by zero is not a defined value like NaN; it’s undefined behavior in C. Also, integers can be divided regardless of sign; negatives are allowed, unlike the idea that division works only for positives.
