Analyze the following code: Code 1: int number = 45; bool even; if (number % 2 == 0) even = true; else even = false; Code 2: int number = 45; bool even = (number % 2 == 0); A: Code 1 has compile errors. B: Code 2 has compile errors. C: Both Code 1 and Code 2 have compile errors. D: Both Code 1 and Code 2 are correct, but Code 2 is better.
