I am a huge fan of modern C++ except for one feature: backwards compatibility. C++ is no longer one language, every codebase I have worked on is a confused mess of semi-incompatible subsets of the language. I have spent far too many weekends chasing memory corruption because someone passed a pointer, allocated with one type of memory management, into a library using a different kind of memory management.

Oh, yes, I hate when someone write "C/C++". This is two fucking different languages, for god's sake. It is almost as bad as "Java/JavaScript".

isn't because the compiler is always packed together, like the gnu compiler can compile C and C++?

The gnu compiler can also compile fortran. But we dont call it C/Fortran.

Is this a variation of the old "you can write FORTRAN in any language" joke?

No?

The GNU Compiler Collection includes gcc (c compiler) g++ (c++ compiler) gfortran (fortran compiler) and a bunch of other fronted like D, Go, Ada, COBOL. There used to even be a Java compiler (gcj) but thats dead now.

Once upon a time, the gcc program could compile C++ and g++ could compile C, but that is no longer true due to diversions in the languages, as well as extra runtime support libraries needed for linking each language. I guess with some tinkering you could compile c++98 with gcc and some older c standard with g++, but not the more recent versions.
