operator overload

[mazaret]

I'm trying to read a list from the standard input in the format [x,y,dx,dy].
Not really good with the operator overloading and how to use it. Actually not even sure if I should use it in this case.
Any ideas?

typing in (ie std input) "[x,y,dx,dy]" in response to cin seems to me to be a very unusual way of entering data.

But if you insist, treat it as a single string and parse the string. Operating overloading could be applied but seems to be an unnecessary complication.
