How do you use the ... operator
In what context? Function parameter lists? Template type parameter lists?
If it's the latter (and possibly the former too), here's a bit on variadic templates: https://kevinushey.github.io/blog/2016/01/27/introduction-to-c++-variadic-templates/
If it's the former (and not the latter), here's a bit on variadic functions: https://www.thegeekstuff.com/2017/05/c-variadic-functions/
Finally, if you're talking about ... as used in catch statements, that's just a catch-all for any exceptions not handled by an earlier catch block.
