Equivalent of NSMutableArray in C++?

Question

What is the C++ object which is the closest to Objective-C NSMutableArray?

Answer 1

std::vector.

See http://www.cplusplus.com/reference/stl/vector/.

Answer 2

NSMutableArray is a heterogeneous container, so: std::vector<std::any>

Before C++17, you could've used something like boost::any instead of std::any.
