    en.wikipedia.org/wiki/Compatibility_of_C_and_C++

    [1] [2] Due to this, development tools for the two languages (such as IDEs and compilers) are often integrated into a single product, with the programmer able to specify C or C++ as their source language. However, C is not a subset of C++, [3] and nontrivial C programs will not compile as C++ code without modification. Likewise, C++ introduces ...

    en.wikipedia.org/wiki/Embedded_C

    Embedded C is a set of language extensions for the C programming language by the C Standards Committee to address commonality issues that exist between C extensions for different embedded systems. Embedded C programming typically requires nonstandard extensions to the C language in order to support enhanced microprocessor features such as fixed ...

  5. Linkage (software) - Wikipedia

    en.wikipedia.org/wiki/Linkage_(software)

    In programming languages, particularly the compiled ones like C, C++, and D, linkage describes how names can or can not refer to the same entity throughout the whole program or one single translation unit. The static keyword is used in C to restrict the visibility of a function or variable to its translation unit. This is also valid in C++.

    Embedded C++ (EC++) is a dialect of the C++ programming language for embedded systems. It was defined by an industry group led by major Japanese central processing unit (CPU) manufacturers, including NEC , Hitachi , Fujitsu , and Toshiba , to address the shortcomings of C++ for embedded applications.

    RTL (C) Callee Return pointer in SI. IA-32: cdecl: Unix-like : RTL (C) Caller When returning struct/class, the calling code allocates space and passes a pointer to this space via a hidden parameter on the stack. The called function writes the return value to this address. Stack aligned on 16-byte boundary due to a bug. cdecl: Microsoft: RTL (C ...

  8. C syntax - Wikipedia

    en.wikipedia.org/wiki/C_syntax

    A snippet of C code which prints "Hello, World!". The syntax of the C programming language is the set of rules governing writing of software in C. It is designed to allow for programs that are extremely terse, have a close relationship with the resulting object code, and yet provide relatively high-level data abstraction.

    An embedded systems programming language, application programming interface (API), and native bytecode compiler toolkit for the Lego Mindstorms RCX platform, Cybermaster and LEGO Spybotics systems. It is intended as a drop-in replacement for the LabVIEW-based ROBOLAB IDE. It is primarily based on the C language but has specific limits, such as ...
