Write one recursive function (a member function of class intSLList discussed in chapter 17)
which displays the contents of a linked list forward then backward. Write a test drive main
program which creates a list object of class intSLList and adds elements to the list and then the
list object should call your function once.
there is an error tells that "base operand of -> has non pointer type IntSLLNode" and another error said that no match for operators != in head !=0 what is that mean please any help?
It means that you have used a pointer indirection operator on a variable that isn't a pointer. Also, that the class or struct intSLList does not have a != operator but yet you have used one in your code.
