How to implement dynamic data structure in C++ like vector?

How dynamic data structure like vectoe can be implemented in C++?

Thanks

vector is a part of C++ so no need to implement it just use it.

Or if you mean how is vector implemented that platform defined but something simple with pointers to start, size and capacity held in the vector itself and dynamic allocation of a buffer to hold the data using new.
