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.
prefix:namespace: string filters a namespace down to one or more pages where string matches the pagename's beginning characters. [13] For example, prefix:help:t finds Help pagenames that begin with "T". When the string has zero characters all pages in the given namespace are found.
A basic search string is simply the topic you are interested in reading about. A direct match of a basic search string will navigate you directly to Wikipedia's article that has that title. A non-match, or any other type of search string will take you to Wikipedia's search results page, where the results of your search are displayed.
Although namespaces are used extensively in recent C++ code, most older code does not use this facility because it did not exist in early versions of the language. For example, the entire C++ Standard Library is defined within namespace std , but before standardization many components were originally in the global namespace.
The std::string type is the main string datatype in standard C++ since 1998, but it was not always part of C++. From C, C++ inherited the convention of using null-terminated strings that are handled by a pointer to their first element, and a library of functions that manipulate such strings.
prefix:namespace: string filters a namespace down to one or more pages where string matches the pagename's beginning characters. [16] For example, prefix:help:t finds Help pagenames that begin with "T". When the string has zero characters all pages in the given namespace are found.
32-bit compilers emit, respectively: _f _g@4 @h@4 In the stdcall and fastcall mangling schemes, the function is encoded as _name@X and @name@X respectively, where X is the number of bytes, in decimal, of the argument(s) in the parameter list (including those passed in registers, for fastcall).
Wikipedia has many talk pages (a.k.a. discussion pages) and other project pages that behave similarly (such as the Help desk, the Village pump, the Reference desk, as well as announcement pages such as the Signpost).
