int i = 0; int i = 0;

The call will most likely be `f(0, 1)` or `f(1, 0)`, but you don't know which. Before C++17, the behavior is undefined, so the behavior could be anything (e.g., `f(2, 2)`).
Technically, the behavior is undefined. Since C++17, this code does not have undefined behavior, but it is still not specified which argument is evaluated first. The call will be `f(1, 2)` or `f(2, 1)`, but you don't know which.
In C++17, this code does not have undefined behavior, but it is still not specified which argument is evaluated first.
