  2. 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.

  3. restrict - Wikipedia

    en.wikipedia.org/wiki/Restrict

    In the C programming language, restrict is a keyword, introduced by the C99 standard, [1] that can be used in pointer declarations. By adding this type qualifier, a programmer hints to the compiler that for the lifetime of the pointer, no other pointer will be used to access the object to which it points.

  4. 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.

  5. Compatibility of C and C++ - Wikipedia

    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    C++ has more complicated rules about pointer assignments that add qualifiers as it allows the assignment of int ** to const int *const * but not the unsafe assignment to const int ** while C allows neither of those (although compilers will usually only emit a warning). C++ changes some C standard library functions to add additional overloaded ...

  6. 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 ...

  7. PC-Lint - Wikipedia

    en.wikipedia.org/wiki/PC-Lint

    Visual Lint provides IDE integration as well as help to understand PC-Lint messages and customizable reports of the lint warnings. [ 4 ] Linticator integrates PC-lint into the Eclipse C/C++ Development Tooling to provide live feedback in the editor and to generate configuration files and suppression markers for PC-Lint.

  8. Rule of three (C++ programming) - Wikipedia

    en.wikipedia.org/wiki/Rule_of_three_(C++...

    The rule of three (also known as the law of the big three or the big three) is a rule of thumb in C++ (prior to C++11) that claims that if a class defines any of the following then it should probably explicitly define all three: [1] destructor; copy constructor; copy assignment operator; These three functions are special member functions. If ...

  9. Thread safety - Wikipedia

    en.wikipedia.org/wiki/Thread_safety

    As interrupt servicing can disable other interrupts, the whole system could suffer. The same function can be implemented to be both thread-safe and reentrant using the lock-free atomics in C++11 : # include <atomic> int increment_counter () { static std :: atomic < int > counter ( 0 ); // increment is guaranteed to be done atomically int result ...
