array of pointers problem

I am trying to display the data from my list using an array that i pass to my class function display(). I can't seem to find any examples for what I am doing in the tutorials. When I attempt to display the list I get the following error.

Code:

---

Unhandled exception at 0x102aec80 (msvcr80d.dll) in list.exe: 0xC0000005: Access violation reading location 0x00000000.

---

I was hoping for a simpler way to accomplish this. But I am very rusty and have to use the trial and error approach. Thanks for any help.

Code:

---

//=========================================================
// DisplayInput
//=========================================================

void displayinput(list & mylist)
{
        int arraysize = 0;
        char ** array;

        mylist.display(array, arraysize);

        for(int i = 0; i < arraysize; i++)
        {
                cout << array[i] << endl;

        }

        for(int i = 0; i < arraysize; i++)
        {
                delete [] array[i];
        }

        delete [] array;

        return;

}

//==========================================================
// Display
//==========================================================

int list::display(char **& array, int & arraysize)
{
    int i = 0;  //for traversing array       
 
    arraysize = num_in_list;

    array = new char*[arraysize];

    node * curr;       
    curr = head;

    while(curr)
    {

        array[i] = new char[60];
        array[i] = '\0';           
        strcat(array[i], curr->fname);   
        strcat(array[i], " " );     
        strcat(array[i], curr->lname);
   
        ++i;

        curr = curr->next;
    }

    arraysize = num_in_list;

      return 0;
}

arraysize is not initialized.

Also, I don't remember if this was asked before, but why aren't you using C++ strings?

Ah. Thanks for the catch. I made the necesary changes (updated posted code), but I still revceive the same error. I probably should begin to use C++ strings. I am relearning some programming so that I can take a class during the summer and my old teachers wouldn't allow us to use C++ strings. Also, I've never used them before.

>> array[i] = '\0';
I think you meant array[i][0] = '\0';

If you really want to learn C++, I'd highly recommend learning the C++ string class and vectors. Modern C++ rarely ever uses C style strings and arrays.

Thank you for the help. That fixed the problem for me. Much appreciated. = )
