And just like any other data type, you can have pointers to classes, pointers to pointers to classes, pointers to pointers to pointers to classes, etc (get the point?). To see how they are implemented, lets take a look at the classic example, the linked-enchilada-list.
#include <iostream.h>
class EnchiladaNode {
public:
int data;
EnchiladaNode* next;
};
void main(void) {
EnchiladaNode *top = new EnchiladaNode;
top->data = 5;
top->next = new EnchiladaNode;
top->next->data = 6;
cout << "First there's a ";
cout << top->data;
cout << " then there's a ";
cout << top->next->data << endl;
delete top->next;
delete top;
}
In the above example there are a few important things to notice and remember.
First of all there is the sytax for accessing class members from a pointer
to a class which is the same as how to access struct members from a pointer to
a struct, using the |
