      English is the C++ of verbal languages: full of weird syntactical bullshit, a huge Feature set noone actually uses more than 5% of, a huge set of undefined behaviors and unexpected edge cases, and a community that swears its the superior language for every kind of application.

      c is incompatible to c++. c++2a is going to add designated initializers, but c is a lot more lax with its type system (outputting warnings where c++ would output errors)

      In some cases it doesn't warn at all, e.g. void* semantics

      converting to void* is implicit in c++, converting back implicitly is an error, doing math on a void* pointer is either a warning or an error, not sure which

      Doing pointer arithmetic on void* is undefined in C but gcc in its infinite wisdom treats this as a warning and a pointer to a size-1 value.

      This is why GCC extensions are bad. Adding new useful syntax is OK (at least it'll error out elsewhere), but making undefined stuff defined? That's a giant minefield. I know I've written code doing void* arithmetic before realizing it was undefined in standard C.
