Answer 1

Cody Gray's answer on Implementing realloc in C left a good impression on me.

It started out simple enough, with the usual remarks about formatting, braces, and declarations. Then it gets more insightful:

• The call to malloc() is buggy.
• The call to memset() is unnecessary.
• The entire my_realloc() function is buggy, and in fact impossible to write without access to the internals of the corresponding malloc function.

Then, there is a heavily commented suggested implementation that explains in detail how it works.

The answer concludes with a general discussion about the complexity of realloc and suggestions on how to tame that complexity.

In all, it's a very thorough and impressive discussion of just 8 lines of code — and Cody's other answers are equally top-notch.

Answer 2

Answer on "Event scheduler in C" by @Herickson. First answer posted March of 2016.

Of the most upvoted answers, this is the first one that reviewed multiple aspects of the code rather than making a single observation. It explains how to use a do/while loop effectively to reduce code length, and it thoroughly covers malloc and null pointers.

Answer 3

I'm going to nominate my answer to the question "Battle game in one 900-line class". From an answerer's perspective, this is one of the answers that I put the most effort into. I came back to the question several times over a period of days. The answer covered various beginner issues from excessive duplication through to misleading line spacing, eventually resulting in a suggested alternate implementation.

Answer 4

Answer on Constructors for a class to represent a price in € or $ by Philip C posted on January 2016.

This topvoted but unfortunately not accepted answer is made as a step by step guide resulting in an easily extensible, maintainable and readable version of the former code.

The answerer explained well how and why the changes should be made.

Answer 5

Denis' answer on Command Tokenizer was exactly what I'm looking for in a good answer. It offered both a critique on the current implementation and suggestions about an alternative approach.

Answer 6

Answer to C++ Blackjack game posted by https://codereview.stackexchange.com/users/4203/forsvarir

It has valid points on:

• Variable scoping
• Domain problem modellini
• Code duplicazione (my personal favourite)
• Bug fixing
• Constant extraction / Naming
