Why? I mean, there is logically (and technically) no difference between
passing a pointer and changing the values pr passing a reference and changing
values. I rarely use references because I don't like it but I would be
interested in knowing what disadvantages this would have. I also encountered a
function where I detected that using references was the only way to solve my
problem.
