We start by understanding the code snippet: int inp = 724395, ans; ans = (inp / 100) % 10;

Step 1: Compute inp / 100. Since inp is an int and the operation is integer division, 724395 / 100 yields 7243 (the decimal part is discarded).

Step 2: Compute 7243 % 10. The modulo operation returns the remainder after division by 10. 7243 divided by 10 gives a remainder of 3.

Now evaluate each option:
- 724: This would correspond to dividing by 1000 or performing a different truncation, but here the computation uses /100 first, which yields 7243, not 724. Thus 724 is not the result.
- 3: This matches the remainder obtained in Step 2, so this value is consistent with the given operations.
- 724.395: This is a floating-point representation. The variables are declared as int, and all operations are integer operations, so a floating-point result cannot occur here.
- Error: There is no syntax or runtime error in the given statements for typical C/C++-style integer arithmetic; the operations are valid and well-defined for int types.

Summarizing the behavior: integer division discards the fractional part, and modulo yields the last digit of the quotient produced by the division by 100. The sequence leads to a final value corresponding to the last digit of 7243, which is 3.
