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.
This requests a memory buffer from the free store that is large enough to hold a contiguous array of N objects of type T, and calls the default constructor on each element of the array. Memory allocated with the new[] must be deallocated with the delete[] operator, rather than delete. Using the inappropriate form results in undefined behavior ...
Queries are issued to an instrument by appending a question-mark to the end of a command. Some commands can be used for both setting and querying an instrument. For example, the data-acquisition mode of an instrument could be set by using the ACQuire:MODe command or it could be queried by using the ACQuire:MODe? command. Some commands can both ...
As an example, std.compat is not a submodule of std, but is named so to indicate the association the module bears to the std module (as a "compatibility" version of it). It has been proposed that additional modules providing other subsets of the standard library be added, which may eventually be included in a future revision.
Tacit programming, also called point-free style, is a programming paradigm in which function definitions do not identify the arguments (or "points") on which they operate. . Instead the definitions merely compose other functions, among which are combinators that manipulate the argumen
The program requests data transfers by use of the read operation. Not all programs require stream input. Not all programs require stream input. For example, the dir and ls programs (which display file names contained in a directory) may take command-line arguments , but perform their operations without any stream data input.
Notice that the object pointed by an auto_ptr is destroyed using operator delete; this means that you should only use auto_ptr for pointers obtained with operator new. This excludes pointers returned by malloc/calloc/realloc , and pointers to arrays (because arrays are allocated by operator new[] and must be deallocated by operator delete[] ).
ColdFusion: the built-in PrecisionEvaluate() function evaluates one or more string expressions, dynamically, from left to right, using BigDecimal precision arithmetic to calculate the values of arbitrary precision arithmetic expressions. D: standard library module std.bigint; Dart: the built-in int datatype implements arbitrary-precision ...
