I assume you're talking about mismatching percent-markers and
arguments, there. That's because of a limitation in C's variadic
function support, ameliorated somewhat by gcc's warnings system, and
completely solved by other languages in which (s)printf can still be
an external function, but with reliable type checking. It's not
whether it's part of the language or not that does that.
