Question

I want to make a custom print function that takes any amount of arguments and prints them all on new lines.

In javascript, the document.write and console.log functions can do this because javascript stores all arguments in an array. To my knowledge, c++ doesn’t do this and can’t because of type restrictions.

So is there a proper way to do this in c++? Take any amount of arguments, regardless of type, and print them all?

Answer 1

You can use a variadic function, similar to printf, but you will still need to know the types of the arguments and how many there are to be able to access them properly.

A better approach would probably be to do something similar to how the << operator was overloaded for ostream or use a chainable function. You will in the end still be limited to types (or supertypes with virtual functions) you know about.
