# 2 complex Vector

2 complex Vector

can you do this for sure and if so how will you start doing i just want make sure you will be able to do it because a lot people here say they can than after i accept the bid before the due date by few hours they say sorry i cant do the assignment it one will be based on array and with size dynamically expanding and shrinking Another one based on linkedlist.
Use a simple vector you created before to create two other more complex vectors with
1) Memory allocation that doubles size of memory when end reached, and 1/2’s memory when the size reaches 1/4.
2) Implemented with a singularly linked list.
