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

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.

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