In computing, inline expansion, or inlining, is a manual or compiler optimization that replaces a function call site with the body of the called function. Inline expansion is similar to macro expansion, but occurs during compilation, without changing the source code (the text), while macro expansion occurs prior to compilation, and results in different text that is then processed by the compiler.
In the C and C++ programming languages, an inline function is one qualified with the keyword inline; this serves two purposes: . It serves as a compiler directive that suggests (but does not require) that the compiler substitute the body of the function inline by performing inline expansion, i.e. by inserting the function code at the address of each function call, thereby saving the overhead ...
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 ...
Parameterized macros are a useful source-level mechanism for performing in-line expansion, but in languages such as C where they use simple textual substitution, they have a number of severe disadvantages over other mechanisms for performing in-line expansion, such as inline functions. The parameterized macros used in languages such as Lisp, PL ...
More macros for querying the characteristics of floating-point types, concerning subnormal floating-point numbers and the number of decimal digits the type is able to store. Anonymous structures and unions , useful when unions and structures are nested, e.g. in struct T { int tag ; union { float x ; int n ; }; }; .
Fixed Expenses vs. Variable Expenses: Quick Take. If you want to make sure you have enough money for necessities and unplanned expenses, you must create a budget. For that, learning the difference ...
Inline vs. prologue – an inline comment follows code on the same line and a prologue comment precedes program code to which it pertains; line or block comments can be used as either inline or prologue; Support for API documentation generation which is outside a language definition
If whitespace is present, the macro is interpreted as object-like with everything starting at the first parenthesis included in the replacement text. Expansion. The preprocessor replaces each token of the code that matches a macro token with the associated replacement text in what is known as macro expansion. Note that text of string literals ...
