Most compilers have at least the following compiler phases (which therefore occur at compile-time): syntax analysis, semantic analysis, and code generation.During optimization phases, constant expressions in the source code can also be evaluated at compile-time using compile-time execution, which reduces the constant expressions to a single value.
Since the machine code emitted by a dynamic compiler is constructed and optimized at program runtime, the use of dynamic compilation enables optimizations for efficiency not available to statically-compiled programs (i.e. those compiled by a so-called "batch compiler", as written below) except through code duplication or metaprogramming.
The category of Member (MIET or TMIET) is open to professional engineers (MIET) and technicians (TMIET) with suitable qualifications and involvement in areas relevant to the interests of the Institution. MIET is a regulated professional title recognised in the European Union by Directive 2005/36.
The official rationale for the 1999 C standard "endorse[d] the principle of maintaining the largest common subset" between C and C++ "while maintaining a distinction between them and allowing them to evolve separately", and stated that the authors were "content to let C++ be the big and ambitious language."

C11 mainly standardizes features already supported by common contemporary compilers, and includes a detailed memory model to better support multiple threads of execution. Due to delayed availability of conforming C99 implementations, C11 makes certain features optional, to make it easier to comply with the core language standard.
C17, formally ISO/IEC 9899:2018, [1] is an open standard for the C programming language, prepared in 2017 and published in July 2018. It replaced C11 (standard ISO/IEC 9899:2011), [2] and is superseded by C23 (ISO/IEC 9899:2024) since October 2024. [3]
Binaries (executables or DLLs) generated with different C++ compilers (like Mingw-w64 GCC and Visual Studio) are in general not link compatible due to the use of different ABIs and name mangling schemes caused by the differences in C++ runtimes. However, compiled C code is link compatible. [12]
