Question:
I need some help with this C++ add function.It adds a new node to the end of the list. I need it to add it to the beginning of the list.
void list::add(string aString){ node* nodePointer = NULL; node* traverser = NULL; while (aString != "end") { if(nodePointer == NULL) { nodePointer = new node (aString); traverser = nodePointer; } else { traverser->next = new node (aString); traverser = traverser->next; } cout << "Another string? "; cin >> aString; }traverser = nodePointer;}
Answer:
You didn’t indicate the purpose of the nodePointer and traverser variables, so I found it awkward to work with your code. But, assuming you used a variable called pHead to point to the head of a singly linked list, you could implement an add function that adds to the beginning of the list like this:
void list::add(NODE* pNode){ pNode->Next = pHead; pHead = pNode;}
