I suggest you to master the methods of debugging, F9 set breakpoints, F10 gradually trackingYou will find that your program is an error, because the head above address is empty, because you void the Create (LINE * head) not return a value, out of the function head life period is over, the solution: to redefine LINE * Create (LINE * head) function return head. The call will return the value assigned to your own definition LINE * head; It is ok to:
LINE * Create (LINE * head)
{
.
Return the head;
}
Void main ()
{
The LINE * head=the Create (head);
.
}
