Thread: Deleted instance

If an instance of a class is deleted with the "delete" command, doesn't it's pointer return to NULL?
If not, how am I going to find out whether an object was deleted or not? Currently I have a program where the same object is deleted twice, and both times it's checked whether the object exists or not (i.e. the pointer is not NULL), yet, ther program gives me a nasty Windows error (the detailed one with the white X on a red traffic board. Dunno what the error is called in english, as I have a Dutch Windows)

No, deleting a pointer does not set it to NULL.

Use something like this to safely delete your dynamic pointers:

Code:

if(ptr)
{
   ptr delete;
   ptr=NULL;
}

//and of course for arrays
if(ptr)
{
   ptr [] delete;
   ptr NULL;
}

thanks for the save, Magos! I'm at work so I was kind of rushing through my reply so I could take care of a phone call.

Code:

#include "Redemption.h"

//for arrays...
if(ptr)
{
   delete [] ptr;
   ptr=NULL
}
