Why is the Process class in the Diagnostics namespace?
Well, according to the documentation, “The System.Diagnostics namespace provides classes that allow you to interact with system processes, event logs, and performance counters.” So I guess by definition it fits. 🙂 But yes, it does seem a bit like an overloading of terms by putting it next to things a bit more obviously diagnostics-related (tracing, …
What’s the point of iter_swap?
From the SGI docs (here): [1] Strictly speaking, iter_swap is redundant. It exists only for technical reasons: in some circumstances, some compilers have difficulty performing the type deduction required to interpret swap(*a, *b).
C++, static vs. namespace vs. singleton
As noted, using global variables is generally bad engineering practice, unless absolutely needed of course (mapping hardware for example, but that doesn’t happen THAT often). Stashing everything in a class is something you would do in a Java-like language, but in C++ you don’t have to, and in fact using namespaces here is a superior …
c++ namespace best practice dilemma
Here’s what I do. In <mylibrary.h>: namespace myproject { namespace mylibrary { namespace impl { using namespace otherlibrary; using namespace boost; using namespace std; using namespace whatever::floats::your::boat; class myclass; class myotherclass; }; using impl::myclass; using impl::myotherclass; }; }; In the source: #include <mylibrary.h> using namespace myproject::mylibrary; //clean!
Should I use a private static member function, or free function in an unnamed namespace?
If the function is only used in one source file, it makes perfect sense to define it there. If nobody else is using it, it doesn’t belong in the header. As you say, it reduces dependencies and can potentially save some recompiles.
Modules vs. Namespaces: What is the correct way to organize a large typescript project?
tl;dr: Do not choose the past. Choose the future: Modules. In early drafts of the ES6 modules specification, there was an inline modules notion, which then has been eliminated in September 2013. However, this notion was already implemented by the TypeScript team, in 2012, with the first beta versions of the language: it was internal …
How to make a namespace alias available only to a class
Namespace alias in the class definition is illegal, as specified by the language specification. Its allowed in only in namespace scope or function scope. You can make an alias at the namespace scope. But this will create a permanent alias which can be used from other files as well. However, the solution is simple: you …
Why do we need both using-directives and include-directives?
using directives and include preprocessor directives are two different things. The include roughly corresponds to the CLASSPATH environment variable of Java, or the -cp option of the java virtual machine. What it does is making the types known to the compiler. Just including <string> for example will make you able to refer to std::string : …
