You compiled c++ code as release ?
Or debug ? Maybe in exe c++ put some extra code, like security or some libs. Minimal visual studio c++ dll 10 kb On fasm 1kb dll |

Last time I tried compile C++ "Hello, world" console app, and get 10,752 bytes, so you're right, it is about 10KB. FASM can be small, you're right again, 1024 bytes. |

Weird. Visual Studio, which I have, has both of these options when I am building my "C" project. And if I look at disassembled codes -- they are different. |

gcc also has debug and release options.
The inclusion of debug symbols is the most obvious difference with regard to size of the output. |

The size of debug symbols aside -- the Released version of code (assembly code) is smaller by some degree.
Register allocation and all that "dark art of optimization techniques". |
