Changing the size of the array allows optimal use of memory.Superfluous elements on the right lost.To reduce fragmentation of memory, change the size of the array is made with a step previously given through the method of Step (int), or 16 (default).

Example:

//--- example for CArrayLong::Resize(int)
#include <Arrays\ArrayLong.mqh>
//---
void OnStart()
  {
   CArrayLong *array=new CArrayLong;
   //---
   if(array==NULL)
     {
      printf("Object create error");
      return;
     }
   //--- add arrays elements
   //--- . . .
   //--- resize array
   if(!array.Resize(10))
     {
      printf("Resize error");
      delete array;
      return;
     }
   //--- delete array
   delete array;
  }
