I'm not too sure what the problem is but it won't allow me to delete the 2nd node. I tried another piece of code but now when i try to delete node 1, it deletes node 8 (the last node), and if i delete node 8, nothing happens.
The code is here: Keep in mind that current is the head pointer pointing to the first node. Disregard my linker and longlinker pointer, that's doing something else. x is the node which the user chooses to delete. Shortlink is the pointer that points the node to the next node.
void ring::remove(int x)
node* prev = current -> shortlink;
node* cur = current;
node* linker = current;
node *longlinker = current;
//cur = prev;
for (int j = 1; j < length; j++)
linker = linker -> shortlink;
for (int k = 1; k < length; k++)
longlinker = longlinker -> shortlink;
for (int i=1; i < length ; i++)
if (prev -> num == x)
cur -> shortlink = prev -> shortlink ;
linker = prev -> shortlink;
longlinker -> longlink= prev -> longlink;
cur = prev;
prev = prev -> shortlink;
