CArray Class
Supports arrays that are similar to C arrays, but can dynamically shrink and grow as necessary.
template < class TYPE, class ARG_TYPE = const TYPE& >
class CArray :
public CObject
Parameters
TYPE
Template parameter specifying the type of objects stored in the array. TYPE is a parameter that is returned by CArray.ARG*_*TYPE
Template parameter specifying the argument type used to access objects stored in the array. Often a reference to TYPE. ARG_TYPE is a parameter that is passed to CArray.
Remarks
Array indexes always start at position 0. You can decide whether to fix the upper bound or allow the array to expand when you add elements past the current bound. Memory is allocated contiguously to the upper bound, even if some elements are null.
As with a C array, the access time for a CArray indexed element is constant and is independent of the array size.
Tipp
Before using an array, use SetSize to establish its size and allocate memory for it. If you do not use SetSize, adding elements to your array causes it to be frequently reallocated and copied. Frequent reallocation and copying are inefficient and can fragment memory.
If you need a dump of individual elements in an array, you must set the depth of the CDumpContext object to 1 or greater.
Certain member functions of this class call global helper functions that must be customized for most uses of the CArray class. See the topic Collection Class Helpers in the MFC Macros and Globals section.
Array class derivation is similar to list derivation.
