Any code style that makes you reorder things when code changes is bad. It would screw up diffs. You are using a version control system right? There’s a few other things that would make your code prettier, but screw up diffs. Imagine this code: int foo = 42; int fooBar = 1024; Now let’s make … Read more
Main reason : To keep compatibility with the existing code, since they have done it with C also. Also have a look at these C++ Coding standards, which presents some generic reasoning regarding the importance of convention. These links discusses about the naming conventions of C/C++ Standard Library. Naming Convention for C API C/C++ Library … Read more
I think enums are safer especially for larger systems with multiple developers. As soon as the need arises to change the value of such an enum, looking up and replacing a string in many places is not my idea of fun 🙂 The most important criteria IMHO is the usage: for use in a module … Read more
First, most of the time you think you need something like this, you don’t; it’s a sign that you’re trying to treat Python like Java, and the solution is to step back and ask why you need a factory. Often, the simplest thing to do is to just have a constructor with defaulted/optional/keyword arguments. Even … Read more
The most important thing is consistency. If there aren’t any coding guidelines for this, then pick one and stick with it. But, if your team already has a de facto standard, don’t change it! That said, I think by far the more common is const int * i; int * const j; because most people … Read more
You could use additional parentheses: subkeyword = ( Session.query(Subkeyword.subkeyword_id, Subkeyword.subkeyword_word) .filter_by(subkeyword_company_id=self.e_company_id) .filter_by(subkeyword_word=subkeyword_word) .filter_by(subkeyword_active=True) .one() )
As @MarcoA.’s answer correctly points out, the suffix _t is largely inherited from C (and in the global namespace – reserved for POSIX). This leaves us with “no suffix” and _type. Notice that there is no namespace-scope name in std ending in _type*; all such names are members of classes and class templates (or, in … Read more
I’m sure that all configuration files(web.config or app.config) are cached by default, so you don’t need to create a static class that holds all values or be afraid that the files are accessed permanently. Here is some reading: Web.Config is Cached ConfigurationManager.RefreshSection Method Application Configuration Files Explained ASP.NET Configuration Overview Regarding to your requirement to … Read more
Besides namespace pollution compilation time (although reducable by precompiled headers, it will hurt those compiling a large project once because they actually want to use it, and not develop – also you want to think about rebuilds which are necessary once in a while) you named “Less figuring out which headers I need and in … Read more
General Decision Before deciding on what to use, I will create a list of criteria that must be met by the library. This could include size, simplicity, integration points, speed, problem complexity, dependencies, external constraints, and license. Depending on the situation the factors involved in making the decision will differ. Generally, I will hunt for … Read more
