You don't need to write destructor for MACListPart. If you do... you don't
want to do the suicide thing...
Remember to decrement itsCount in the
void MACList::DeleteNode (const String &mac) function and you'll get...

First of all thank you for your answer
Secondly .. how did you do that ??
I did put
if(this != NULL)
{
delete this;
}
else delete this;
in comments and still the program hangs !! Can you give me the
destructor of your String class ????
I even removed the destructor definition in the MACListPart , so the
compiler should do whatever it want to, when deleting the node .
But still nothing !!! .
This is the output of my program :
Calling the default destructor of String ..
Default destructor of called ...

I am not THAT stupid ... When I i say it hangs i mean that the
execution of the program stops and Windows XP creates a window
which says that " LinkedList3.exe has encourted a problem and needs
to close . We are sorry for the inconvenience " blah-blah .. Debug ,
Send Report , Don't Send ". The problem is with the delete operation .
Did you run this program with VC++ ??? . What's your String destructor
???

If this is NULL you have problems, therefore this check is completely

The reason it crashes is because you dont exit the loop. Just add a
break; here. Or if you want to delete all nodes that match update
prevNode and currNode.

One of the things that would give me that message is running out of stack
space.
This...
MACListPart::~MACListPart (void) {
cout << "Calling the default destructor for MACListPart ...\n";
if (this != NULL)
delete this;
else
delete this;
}
.... will set up an endless loop and would have caused that.that message for
me.
Did you run this program with VC++ ???.
....and two others... g++ amd Borland
What's your String destructor ???
Well I don't have your String class but your d'tor looks OK and would have
worked for you elsewhere in your program.
I used std::string, implemented thus...
#include <malloc.h>
#include <stdio.h>
#include <stdlib.h>
#include <iostream.h>
// #include "GenericStringClass2.h"
#include <string.h>
// Emulate 'class String'
#include <string>
typedef std::string String;
#define GetString c_str
#define DEFAULT 0
<snip>
,,,You could try that.

Many of these headers are not necessary in your program. Also, you

If "current" is used only to help insertions at the end of the list,
its name is misleading; also, you may need to update it when you
delete a node.
} // increasing the elements of the list itsCount++; }
(...)
The problem is when i am trying to delete a node .. The program hangs after the command delete currNode is executed ... The String class is declared in another file and here is the default destructor :
Hard to say anything without the complete String class, but you could
for example replace it with std::string (or, better yet, int) for
testing MACList separately.

You forgot to update pMacListPart.
(...) void MACList::AddNode(const String& mac) { MACListPart *pMACListPart = new MACListPart; pMACListPart->macAdr=mac; pMACListPart->data=DEFAULT; pMACListPart->next=NULL;
if(IsListEmpty() == true) { head=pMACListPart; current=head; } else // (if IsListEmpty() == false ) { current->next=pMACListPart; current=pMACListPart;
If "current" is used only to help insertions at the end of the list, its name is misleading; also, you may need to update it when you delete a node.
} // increasing the elements of the list itsCount++; }
(...)
The problem is when i am trying to delete a node .. The program hangs after the command delete currNode is executed ... The String class is declared in another file and here is the default destructor :
Hard to say anything without the complete String class, but you could for example replace it with std::string (or, better yet, int) for testing MACList separately.
