Z Don’t skip these questions! Even if you’re too lazy to sit down and seriously think about each answer (believe me, you’ll gain a lot from doing so), at least read the questions and consider them in passing. The final part of this book contains answers and discussion for each of these questions. It’s not a straight answer set—few of the questions have a definite yes or no response. Once you’ve thought about them, compare your answers with mine. Many of my “answers” contain extra information that isn’t covered in the main chapter.
It’s a nice luxury, but don’t be lulled into a false sense of security. You still have to think. You have to explicitly drop references to objects you no longer care about, or they won’t be cleaned up; don’t accidentally hold on to an object reference. , A refers to B, and B refers to A, but no one else cares about them). This could cause objects to never be swept up; a subtle form of memory leak. Initialize All Variables at Their Points of Declaration This is a clarity issue. The intent of each variable is explicit if you initialize it.

Make everything as const as you possibly can. It does two things: const qualifications act as code documentation, and const allows the compiler to spot silly mistakes that you make. It prevents you from modifying data that’s off-limits. Constraints We’ve thought about the set of assumptions we make as we program.
