The scope of anonymous classes is confined to their parent class, so the compiler must produce a "qualified" public name for the inner class, to avoid conflict where other classes with the same name (inner or not) exist in the same namespace. Similarly, anonymous classes must have "fake" public names generated for them (as the concept of ...
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
C++ Description Simply expands to an immutable string. This template is a mere level of indirection for all C++-related templates, such as User C++, User C++-1, etc. Since there has been discussion about whether using a lowercase or uppercase 'c' in the text shown to the user, this provides a single point of modification in case we need it.
Some compilers (for languages such as C++) combine namespaces and names for internal use in the compiler in a process called name mangling. As well as its abstract language technical usage as described above, some languages have a specific keyword used for explicit namespace control, amongst other uses. Below is an example of a namespace in C++:
The gSOAP tools convert C/C++ data types to/from XML schema data types. Since C does not support namespaces and struct/class member names cannot be namespace-qualified in C++, the use of identifier naming conventions in gSOAP allow for binding this structure and its members to an XML schema complexType that is auto-generated as follows:
A using namespace:: std declaration above or within main can be issued to apply the ::std:: prefix automatically, although it’s generally considered poor practice to use it globally in headers because it pollutes the global namespace. [43] A few of the C++≥98 versions of C’s headers are missing; e.g., C≥11 <stdnoreturn.h> and <threads.h ...
In the C++ Standard Library, several algorithms use unqualified calls to swap from within the std namespace. As a result, the generic std::swap function is used if nothing else is found, but if these algorithms are used with a third-party class, Foo, found in another namespace that also contains swap(Foo&, Foo&), that overload of swap will be used.
As with the collision of other identifiers, it must be resolved in some way [a] for the new software (such as a mashup) to work right. [1] Problems of name collision, and methods to avoid them, are a common issue in an introductory level analysis of computer languages, such as for C++. [1]
