direct.h is a C/C++ header file provided by Microsoft Windows, which contains functions for manipulating file system directories. Some POSIX functions that do similar things are in unistd.h . Member functions
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 general, based on a makefile, Make updates target files from source files if any source file has a newer timestamp than the target file or the target file does not exist. For example, this could include compiling C files ( *.c ) into object files , then linking the object files into an executable program.
Iterators can provide a consistent way to iterate on data structures of all kinds, and therefore make the code more readable, reusable, and less sensitive to a change in the data structure. An iterator can enforce additional restrictions on access, such as ensuring that elements cannot be skipped or that a previously visited element cannot be ...
They can be used to iterate over any object that implements the NSFastEnumeration protocol, including NSArray, NSDictionary (iterates over keys), NSSet, etc. NSArray * a = [ NSArray new ]; // Any container class can be substituted for ( id obj in a ) { // Dynamic typing is used.
The C++ Standard Library is based upon conventions introduced by the Standard Template Library (STL), and has been influenced by research in generic programming and developers of the STL such as Alexander Stepanov and Meng Lee. [4] [5] Although the C++ Standard Library and the STL share many features, neither is a strict superset of the other.
A glob-style interface for returning files or an fnmatch-style interface for matching strings are found in the following programming languages: C and C++ do not have built-in support for glob patterns, however on Unix-like systems, C and C++ may include <glob.h> from the C POSIX library to use glob().
windows.h is a source code header file that Microsoft provides for the development of programs that access the Windows API (WinAPI) via C language syntax. It declares the WinAPI functions, associated data types and common macros. Access to WinAPI can be enabled for a C or C++ program by including it into a source file: #include <windows.h>
