Use STL list class for this

The STL list class is a template class of sequence containers that maintain their elements in a linear arrangement and allow efficient insertions and deletions at any location within the sequence. The sequence is stored as a bidirectional linked list of elements, each containing a member of some type Type.

template <
   class Type,
   class Allocator=allocator<Type>
>
class list
Parameters
Type
The element data type to be stored in the list. (can be future or reservation class types)
Allocator
The type that represents the stored allocator object that encapsulates details about the list's allocation and deallocation of memory. This argument is optional, and the default value is allocator<Type>.


You can refer to the code for insert at
