That makes sense to me.
That makes sense to me.
I made the changes and some errors occured so I changed the things in bold. It executes without errors but my output is still displaying only the first element as before with blank lines for the other elements.
I am going crazy with this program. Please help me, if you can. Thanks.
Code:void HybridList::Insert( /* in */ me item ) // Precondition: // component members of list nodes are in ascending order // && item is assigned // Postcondition: // New node containing item is in its proper place // in linked list // && component members of list nodes are in ascending order { mePtr currPtr; // Moving pointer mePtr prevPtr; // Pointer to node before *currPtr mePtr newMePtr; // Pointer to new node // Set up node to be inserted newMePtr = new me; newMePtr->lName = item.lName; // Find previous insertion point prevPtr = NULL; currPtr = head; while (currPtr != NULL && item.lName > currPtr->lName) // Error with this line { prevPtr = currPtr; currPtr = currPtr->link; } // Insert new node newMePtr->link = currPtr; if (prevPtr == NULL) head = newMePtr; else prevPtr->link = newMePtr; }
What I see
newMePtr->lName = item.lName;
you initialize only lName in your stored data
If you want to store all strings you should copy all strings...
maybe something like
*newMePtr = item;
will work
also - to avoid unnecesary copying, I think you should pass me as const reference
void HybridList::Insert( /* in */ const me& item )
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

It works vart. Thank you.
Last question, I am currently outputting the list to the screen but I need it to print to a file called 'contact.dat'. How can I go about that in the Hybrid class print function?
Thanks
Look at a tutorial on file I/O. It's not a difficult thing.
I figured it out. I was forgetting to use include <fstream>. Thanks for all of the help and I really appreciate the help.
Check out this link to know more.Code:#include <fstream> fstream binary_file("'contact.dat'.",ios::binary|ios::out); binary_file.write(reinterpret_cast<char *>(currPtr),sizeof(me)); binary_file.close();
EDIT: It seems like I didn't post it in time.Sorry can't help much.
