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
The included document can itself be another SSI-enabled file. The file or virtual parameters specify the file (HTML page, text file, script, etc.) to be included. NCSA HTTPd did not support CGI via include, [2] but later Apache HTTPd does. [7] If the process does not have access to read the file or execute the script, the include will fail.
The C++ Standard Library provides several generic containers, functions to use and manipulate these containers, function objects, generic strings and streams (including interactive and file I/O), support for some language features, and functions for common tasks such as finding the square root of a number.
A basic_string is guaranteed to be specializable for any type with a char_traits struct to accompany it. As of C++11, only char, wchar_t, char16_t and char32_t specializations are required to be implemented. [16] A basic_string is also a Standard Library container, and thus the Standard Library algorithms can be applied to the code units in ...
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 a single compilation unit, and is useful for evaluating macro-containing contents multiple times against changing definitions of the macro.
Wt (pronounced "witty") is an open-source widget-centric web framework for the C++ programming language. It has an API resembling that of Qt framework (although it was developed with Boost, and is incompatible when mixed with Qt), also using a widget-tree and an event-driven signal/slot system.
The five living U.S. presidents — Joe Biden, Donald Trump, Barack Obama, George W. Bush and Bill Clinton — reunited to honor the life and legacy of Jimmy Carter. On Thursday, Jan. 9, a date ...
The C library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O. It does not include a standard set of " container types " like the C++ Standard Template Library , let alone the complete graphical user interface (GUI) toolkits, networking tools, and profusion of other ...
