Question

well i need to make a class called TList which have a private attribute and a counter

private:
    TPerson **pListe;
     int counter;

TPerson is another class i made before. counter is to know the position of the array.
So i need to create a List which have methods like

Add(TPerson *p), Delete(TPerson *p)

Now my problem is:
how can i add those TPerson objects to my double pointer list?

i’ve my

void TListe::Add(TPerson &p) {...}

method.

i tryed it like that:
pListe[counter] = &p;

for example and it doesnt work.. can somebody explain me how i need to work with double pointer arrays and use them as lists?

greetings

I’m confused by your code example , *pListe is going to hold pointer to first element of array of TPerson objects, or just pointer to TPerson ?. I think you you need to first allocate array of pointers to person :

pListe = new TPerson* [size];

then you can do:

Add(TPerson* p) {
pListe[some_counter_to_past_the_last_element] = p;
...
}

Add(TPerson& p) {
pListe[some_counter_to_past_the_last_element] = &p;
...
}
