  2. C standard library - Wikipedia

    en.wikipedia.org/wiki/C_standard_library

    (By default, Microsoft Visual Studio’s C and C++ compilers issue warnings when using older, "insecure" functions. However, Microsoft’s implementation of TR 24731-1 is subtly incompatible with both TR 24731-1 and Annex K, [16] so it’s common for portable projects to disable or ignore these warnings. They can be disabled directly by issuing

  3. include guard - Wikipedia

    en.wikipedia.org/wiki/Include_guard

    For #include guards to work properly, each guard must test and conditionally set a different preprocessor macro. Therefore, a project using #include guards must work out a coherent naming scheme for its include guards, and make sure its scheme doesn't conflict with that of any third-party headers it uses, or with the names of any globally visible macros.

  4. C++ Standard Library - Wikipedia

    en.wikipedia.org/wiki/C++_Standard_Library

    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.

  5. pragma once - Wikipedia

    en.wikipedia.org/wiki/Pragma_once

    Using #pragma once allows the C preprocessor to include a header file when it is needed and to ignore an #include directive otherwise. This has the effect of altering the behavior of the C preprocessor itself, and allows programmers to express file dependencies in a simple fashion, obviating the need for manual management.

  6. Type safety - Wikipedia

    en.wikipedia.org/wiki/Type_safety

    In computer science, type safety and type soundness are the extent to which a programming language discourages or prevents type errors.Type safety is sometimes alternatively considered to be a property of facilities of a computer language; that is, some facilities are type-safe and their usage will not result in type errors, while other facilities in the same language may be type-unsafe and a ...

  7. windows.h - Wikipedia

    en.wikipedia.org/wiki/Windows.h

    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>

  9. Access modifiers - Wikipedia

    en.wikipedia.org/wiki/Access_modifiers

    Access modifiers are a specific part of programming language syntax used to facilitate the encapsulation of components. [1] In C++, there are only three access modifiers. C# extends the number of them to six, [2] while Java has four access modifiers, but three keywords for this purpose. In Java, having no keyword before defaults to the package ...
