To be clear the equivalent C++ code is:

    #include <windows.h>
    extern "C" __declspec(dllimport) int __stdcall MessageBoxA(HWND, LPCSTR, LPCSTR, UINT);
    // or
    extern "C" __declspec(dllimport) int __stdcall MessageBoxA(void *, const char[], const char[], unsigned int);

It's not exactly a stellar improvement.

Lol, no this is the equivalent

  #include <windows.h>

 int main() {
      MessageBoxA(NULL, "world!", "Hello", 0);
      return 0;
  }
