Variadic template

Do you know those boxes where you put your toys in? Imagine you have one big box that can hold different kinds of toys, like big animals or small cars or even strange shaped objects.

A variadic template is like that big box. It can hold different types of inputs, like numbers or words or anything else you can think of. It's a fancy way for a computer program to be able to work with many different inputs without needing to know or care what those inputs are ahead of time.

Just like you can take your toys out of the box one at a time or all at once, a variadic template can process each input separately or all of them together. So it's a really useful tool for programmers who need to write code that works with a lot of different inputs, no matter what they might be.
