I saw these while I was learning about vectors, where they define the type of variables in the vector.
I thought that it might help with functions.

btw.
Is there a way for a function to return multiple variable types?

What I have tried:

I can't find anything describing this.

It amazes me how they can use Google Search to find the CodeProject Q&A to ask these questions yet can't use it to research for a solution to this stuff... go figure...

Yes, if I got you: a template function may do that. See, for instance: Function template - cppreference.com[^].
