I'm working on a program that's got 2 classes: #1 = a node class and #2
= a linked_list class. The node class looks like:
class Node {
private:
char * SomeString; // length determined at run-time
public:
void SomeFunction();
};
class linked_list {
private:
Node * ANode;
public:
void build_it();
};
file: linked_list.cpp
void linked_list::build_it()
{
ANode = new Node();
I'm OK so far, so now I compute just how much space I'll need for
SomeString. The question I have is - how can I allocate that space?
ANode->SomeString = new char[CalculatedNumber];
This doesn't work in build_it() because SomeString is a private variable
in class Node. In order to allocate the space, do I need to declare
SomeString as protected? Would deriving linked_list from Node allow me
access to private variables in Node from linked_list?
