Function argument order of evaluation

[Tadeus Prastowo]

Hello,

In C/C++, the following code has an undefined behavior (UB):

int my_var = 1;
my_function((my_var = 10), 2 * my_var);

It is because their respective standards do not specify that the
assignment `(my_var = 10)' as the first argument must be evaluated
before the second argument `2 * my_var' is evaluated.  So,
`my_function' can see as its arguments either `10' and `20' or `10'
and `2'.  Compiling the following code with GCC 5.5 that comes with
Ubuntu 16.04 gives the latter:

#include <stdio.h>
void my_function(int a, int b) {
  printf("%d, %d\n", a, b);
}
int main() {
  int my_var = 1;
  my_function((my_var = 10), 2 * my_var);
  return 0;
}

Does Emacs Lisp behave the same or does it provide a guarantee that
the function arguments are always evaluated from left to right?

I have searched Emacs Lisp manual and the archive of this mailing list
for the keyword "order of evaluation" but have not found the answer.
So, I ask directly here.  Sorry if I might have missed the obvious.

Thank you for your kind help.
