The first application run in such a context is a more sophisticated and powerful macro compiler, written in the machine-independent macro language. This macro compiler is applied to itself, in a bootstrap fashion, to produce a compiled and much more efficient version of itself. The advantage of this approach is that complex applications can be ...
A variadic macro is a feature of some computer programming languages, especially the C preprocessor, whereby a macro may be declared to accept a varying number of arguments. Variable-argument macros were introduced in 1999 in the ISO/IEC 9899:1999 ( C99 ) revision of the C language standard, and in 2011 in ISO/IEC 14882:2011 ( C++11 ) revision ...
Due to its limitations, C and C++ language features have been added over the years to minimize the value and need for the preprocessor. Constant. For a long time, a preprocessor macro provided the preferred way to define a constant value. An alternative has always been to define a const variable, but that results in consuming runtime memory.
In 1989, C++ 2.0 was released, followed by the updated second edition of The C++ Programming Language in 1991. [32] New features in 2.0 included multiple inheritance, abstract classes, static member functions, const member functions, and protected members. In 1990, The Annotated C++ Reference Manual was published. This work became the basis for ...
The definition of the list's elements. Expansion(s) of the list to generate fragments of declarations or statements. The list is defined by a macro or header file (named, LIST) which generates no code by itself, but merely consists of a sequence of invocations of a macro (classically named "X") with the elements' data.
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.
It is not to be confused with macros, the mechanism often found in programming languages (like C or Scala) to express substitution rules for program pieces. Macroprogramming originated in the context of wireless sensor network programming [ 3 ] [ 4 ] [ 5 ] and found renewed interest in the context of the Internet of Things [ 6 ] and swarm ...
A macro is a piece of code that executes at compile time and either performs textual manipulation of code to-be compiled (e.g. C++ macros) or manipulates the abstract syntax tree being produced by the compiler (e.g. Rust or Lisp macros). Textual macros are notably more independent of the syntax of the language being manipulated, as they merely ...
