C equivalent of C vector with contiguous memory

Question

What s the C  equivalent of C   vector    I am searching for this feature   To have a dynamic array of contiguously stored memory that has no performance penalty for access vs  standard arrays   I was searching and they say  NET equivalent to the vector in C   is the ArrayList  so   Do ArrayList have that contiguous memory feature

You could use a List lt T gt  and when T is a value type it will be allocated in contiguous memory which would not be the case if T is a reference type   Example   List lt int gt  integers   new List lt int gt     integers Add 1   integers Add 4   integers Add 7    int someElement   integers 1

First of all  stay away from Arraylist or Hashtable  Those classes are to be considered deprecated  in favor of generics  They are still in the language for legacy purposes   Now  what you are looking for is the List lt T gt  class  Note that if T is a value type you will have contiguos memory  but not if T is a reference type  for obvious reasons

use List lt T gt   Internally it uses arrays and arrays do use contiguous memory

C  has a lot of reference types  Even if a container stores the references contiguously  the objects themselves may be scattered through the heap
