This example will use "ExampleClass". A notable difference between C++ and Objective-C when making use of these implementation files is the extensions used at the end of the files. In C++ it will be .cpp [14] and in Objective-C it will be .m, [15] but both will use the same .h extension for their header file(s) [16] [17] as shown in the example ...
For example, basic_fstream<CharT,Traits> refers to the generic class template that implements input/output operations on file streams. It is usually used as fstream which is an alias for basic_fstream<char,char_traits<char>> , or, in other words, basic_fstream working on characters of type char with the default character operation set.
The select and poll system calls allow a set of file descriptors to be monitored for a change of state, e.g. when data becomes available to be read. For example, consider a program that reads from a continuously updated file and displays its contents in the X Window System, which communicates with clients over a socket (either Unix domain or ...
Below is an example written in Java that takes keyboard input and handles each input line as an event. When a string is supplied from System.in , the method notifyObservers() is then called in order to notify all observers of the event's occurrence, in the form of an invocation of their update methods.
In computing, a sink, or data sink generally refers to the destination of data flow.. The word sink has multiple uses in computing. In software engineering, an event sink is a class or function that receives events from another object or function, while a sink can also refer to a node of a directed acyclic graph with no additional nodes leading out from it, among other uses.
SystemC is a set of C++ classes and macros which provide an event-driven simulation interface (see also discrete event simulation).These facilities enable a designer to simulate concurrent processes, each described using plain C++ syntax.
The C++ standard library is a collection of utilities that are shipped with C++ for use by any C++ programmer. It includes input and output, multi-threading, time, regular expressions, algorithms for common tasks, and less common ones (find, for_each, swap, etc.) and lists, maps and hash maps (and the equivalent for sets) and a class called vector that is a resizable array.
The C preprocessor (used with C, C++ and in other contexts) defines an include directive as a line that starts #include and is followed by a file specification. COBOL defines an include directive indicated by copy in order to include a copybook. Generally, for C/C++ the include directive is used to include a header file, but can
