c++ - How to make a class with 'dynamic' data types?

Question

In the C++ standard library, there is std::vector, and you can specify the type you want to put into a vector while declaring it.

I want to create a class which would contain a vector of either strings, or ints, or whatever I would ever need. Is it possible to do this in an easy way, or would I have to write thousands of lines in C and assembly?

Answer 1

C++ has variant and any. Variant supports a fixed list of alternative types; any supports any type of object that can be copied.

Now, any is really tricky to use right; in order to get back your data, you have to know what type of data (exactly) is in the any. And often variant is all you need.

If your goal is something akin to a json structure, well there are plenty of implementations of that.
