Is c++ language different every compiler like in code block with dev

Answer 1

C++ is only an ISO standard for a language with individual compilers being developed to conform to this standard. Not all compilers support all new or older standard features of C++ or even the same standard library.

Compilers like MSVC, GCC, and clang (I think at least mostly) support the entire lastest standard (c++17) and some additional experimental features coming in C++20.
