| Quality | Example |

| Larger |
"The g++ version is a little larger than the gcc version but not 100x larger" from question "How does the size of compiled binaries depend on the used libraries? c/c++" |
| Looser |
"Unfortunately g++ packed the structs significantly looser than gcc which caused significant problems sharing objects between c and c++ code" from question "Is it possible to subclass a C struct in C++ and use pointers to the struct in C code?" |
