Please read the posting guidelines[^] before posting. 1) Use the pre tag to format your code properly so that it is readable. 2) Ask a question. Dumping your code without explaining what the problem is not very useful. We can't read minds you know.

what error ? compile error ? runtime error ? did you try to "run" your program manually on paper (i.e. follow each step manually to see if your algo is at least valid ) ? did you try debugging it with a debugger ?

You might start here. Once you get that corrected, you should do some serious cleanup to the
create()function. No screen I/O should be performed in that function. Prompt the user for input elsewhere and pass that data to thecreate()function. Also, the call tonewinside thewhile()loop is wrong. Is each new node added to the front of the list or the rear? If the front, nowhile()loop is necessary. If the rear, thewhile()loop should simply iterate each node untilNULLis reached."One man's wage rise is another man's price increase." - Harold Wilson
