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
In this case, the direct determination for which API is available would make use of the fact that the include file had advertised itself with its #include guard macro. The #include directive is defined to represent a programmer's intention to actually include the text of a file at the point of the directive. This may occur several times within ...

When T has the nested type foobar defined, the instantiation of the first test works and the null pointer constant is successfully passed. (And the resulting type of the expression is yes .) If it does not work, the only available function is the second test , and the resulting type of the expression is no .
In computer programming, a precompiled header (PCH) is a (C or C++) header file that is compiled into an intermediate form that is faster to process for the compiler.Usage of precompiled headers may significantly reduce compilation time, especially when applied to large header files, header files that include many other header files, or header files that are included in many translation units.
Target A Target contains a set of tasks for MSBuild to execute. The focus of MSBuild is the result Target specified when invoking MSBuild with the project file. This is because a Project may contain several Target entries, each executed sequentially (and conditionally). Subsequent dependent Targets are executed before the requested Target.
An illustration of the linking process. Object files and static libraries are assembled into a new library or executable. A linker or link editor is a computer program that combines intermediate software build files such as object and library files into a single executable file such a program or library.
Another approach is to use the Boehm garbage collector, a conservative garbage collector that replaces standard memory allocation functions in C and C++ with a garbage collector. This approach completely eliminates dangling pointer errors by disabling frees, and reclaiming objects by garbage collection.
