How to get the data type of a std::any variable?

Question

std::any var = 1;

How can you get the type of var?

For example:

std::cout << GetTypeOf(var) << std::endl;

Output:

int

I have tried std::cout << typeid(out).name() << std::endl; but it returns std::array — anom, May 08 '21 at 10:15
Note that `type_info::name` is implementation defined, it may or may not be `"int"`, but it is unlikely to be `"std::array"` unless there *is* and `std::array` of some sort in there. Please show a [mcve]. — n. m. could be an AI, May 08 '21 at 10:19

std::cout << var.type().name() << std::endl;

Note that the exact output of name() is implementation-defined, so you may get i instead of int for example.
