Redundant code constructs
- by Diomidis Spinellis
The most egregiously redundant code construct I often see involves using the code sequence if (condition) return true; else return false; instead of simply writing return (condition); I've seen this beginner error in all sorts of languages: from Pascal and C to PHP and Java. What other such constructs would you flag in a code review?Read the article

Should I use block identifiers ("end;") in my code?
- by JosephStyons
Code Complete says it is good practice to always use block identifiers, both for clarity and as a defensive measure. Since reading that book, I've been doing that religiously. Sometimes it seems excessive though, as in the case below. Is Steve McConnell right to insist on always using block identifiers? Which of these would you use? //naughty…Read the article

C++ iterators & loop optimization
- by Quantum7
I see a lot of c++ code that looks like this: for( const_iterator it = list.begin(), const_iterator ite = list.end(); it != ite; ++it) As opposed to the more concise version: for( const_iterator it = list.begin(); it != list.end(); ++it) Will there be any difference in speed between these two conventions? Naively the first…Read the article

How to name variables which are structs
- by evilpie
Hello, i often work on private projects using the WinApi, and as you might know, it has thousands of named and typedefed structs like MEMORY_BASIC_INFORMATION. I will stick to this one in my question, what still is preferred, or better when you want to name a variable of this type. Is there some kind of style guide for this case? For…Read the article

Style question about existing piece of code (C/C++)
- by Leif Ericson
I just hope the following doesn't seem to you like redundant jabber :) Anyway, there is that: for (p = fmt; *p; p++) { if (*p != '%') { putchar(*p); continue; } switch (*++p) { /* Some cases here */ ... } } And I wondered why the writer (Kernighan / Ritchie) used the continue in the if…Read the article

Best ways to construct Dynamic Search Conditions for Sql

I have always wondered what's the best way to achieve this task. In most web based applications you have to provide search options on many different criteria.

When naming a boolean, or a function returning a boolean it's usual to prefix with 'is' e.g. isPointerNull isShapeSquare What about when refering to multiple items, should it be: arePointersNull or isPointersNull areShapesNull or isShapesNull I can see arguments for both; is offers consistency and perhaps slightly…Read the article

Purpose of IF, ELSE, FOR macros ?
- by psihodelia
I have a source code of a library which has a lot of strange IF, ELSE, FOR, etc. macros for all common C-keywords instead of using just usual if,else,for,while keywords. These macros are defined like this: #define IF( a) if( increment_if(), a) where increment_if() function is defined so: static __inline void…Read the article

Is it a good idea to apply some basic macros to simplify code in a large project?
- by DoctorT
I've been working on a foundational c++ library for some time now, and there are a variety of ideas I've had that could really simplify the code writing and managing process. One of these is the concept of introducing some macros to help simplify statements that appear very often, but are a bit…Read the article
