Order of evaluation of arguments in function calling?

Question

I am studying about undefined behavior in C and I came to a statement that states that

there is no particular order of evaluation of function argume

Answer 1

so finally i found it...yeah. it is because the arguments are passed after they are evaluated.So passing arguments is a completely different story from the evaluation.Compiler of c as it is traditionally build to maximize the speed and optimization can evaluate the expression in any way.
so the both argument passing and evaluation are different stories altogether.
