I just started learning c++ (coming from java) and am having some serious problems with doing anything :P Currently, i am attempting to make a linked list, but must be doing something stupid cause i keep getting "void value not ignored as it ought to be" compile errors (i have it marked where it is throwing it bellow). If anyone could help me with what im doing wrong, i would be very grateful :)
Also, I am not used to having the choice of passing by reference, address, or value, and memory management in general (currently i have all my nodes and the data declared on the heap). If anyone has any general advice for me, i also wouldn't complain :P
Key code from LinkedListNode.cpp
LinkedListNode::LinkedListNode()
{
//set next and prev to null
pData=0; //data needs to be a pointer so we can set it to null for
//for the tail and head.
pNext=0;
pPrev=0;
}
/*
* Sets the 'next' pointer to the memory address of the inputed reference.
*/
void LinkedListNode::SetNext(LinkedListNode& _next)
{
pNext=&_next;
}
/*
* Sets the 'prev' pointer to the memory address of the inputed reference.
*/
void LinkedListNode::SetPrev(LinkedListNode& _prev)
{
pPrev=&_prev;
}
//rest of class
Key code from LinkedList.cpp
#include "LinkedList.h"
LinkedList::LinkedList()
{
// Set head and tail of linked list.
pHead = new LinkedListNode();
pTail = new LinkedListNode();
/*
* THIS IS WHERE THE ERRORS ARE.
*/
*pHead->SetNext(*pTail);
*pTail->SetPrev(*pHead);
}
//rest of class
