Linked List Question

    I searched the forum for Linked lists and got some results but they didn't really help much so here goes.

    I'm doing a college project and I'm almost finished but I've run into a problem. The task is to maintain a doubly linked list of names. The program breaks when I try to insert an item or delete an item. From what I can tell it's the srtcmp bit in the insert and erase procedures thats causing the problem I just don't know how to fix it. Any help would be really appreciated.

    The code I have so far is in the attached file. It's in a text file so you'll have to resave it as a .cpp file.


    Cheers
    Rory

    while(curr != NULL || strcmp(curr->Name,arr)

    You are using an || statement. curr can be null on the left side of the condition and when it goes to evaluate the right side of the condition curr->Name will be null. This is causing your error. Didnt look over the code in detail but maybe you need to use and && statement instead?
