could also be "4" or 4! 4 seems like it would be the most evil option, honestly

The real evil option is C: 2+"22" = 0, 4+"4" = undefined behavior and probably the value of some other variable.

The real horror is "1d9" + 1 = 2, as does PHP: https://3v4l.org/Dn6Sm

I think you meant: "22"+2 = "", and it is not UB to make the second pointer, only to use it

The pointer arithmetic works both ways, same as square brackets.

or the most sane, depending on context... e.g. awk and perl do this.
