[C++] One way to convert pointer of structure to vector

Of course, you can choose one method of C++ likes reinterpret which is described in below topic:
https://www.geeksforgeeks.org/reinterpret_cast-in-c-type-casting-operators/

However, it is easily to find out one big problem in here is:
reinterpret_cast is a very special and dangerous type of casting operator

In embedded system, this problem is not allowed. Then, we should convert it by manually.
The idea is, you push each structure to vector by passing number of structure to function which is used for converting.
