Lists in C++

I have a list named CListe of objects from CEnsemble, and declared as follows:

class CListe; //forward declaration

class CEnsemble
{
...
  CListe *SCList;
...
}

class CListe
{
...
}

As you can see, there´s a list inside each element which compose the list.

I try to initialize the list inside each element in the CEnsemble´s contructor, as follows:

CEnsemble::CEnsemble(){    
   ...
   SCList->init();
}

But when I try to run the program, I get an error in this initialization:

"This program has performed an illegal operation and will be shut down. If the problem persistes...  Close/Debug/Details"

This error has nothing to do with the init method itself, since I get the error even for very simple methods.

HELP!!!!

Hi,
The problem is obviously in fact that you do not create CListe object. So before running init you should call CListe constructor like: SCList = new SCList(...);
Also note that you posted this question twice.

Hey, I was first (check the other Q), though it doesn't really matter.

As I mentioned, this is a likely cause of the problem, but one can't be sure because the code given is incomplete.

Happens all the time, and as I said, no problem.

I'm still curious about the rest of the code. The dots indicate some of it has been left out and what's left is too little.

Hey if u want another solution u can try this :-

class CListe
{
....
  int data;
  CListe *SCList;
....
}

CEnsemble::CEnsemble(){      
   ...
   SCList = NULL;
}

And just in the main declare an object of the class  to create the list

main()
{
    CListe list;
......
}

you can access the elements like:-

     int a = list->data;

try this and tell me the results.
if u have any probs. please contact me at jamanat@usa.net
