C++ Pointer Lists and passage by reference


C++ Pointer Lists and passage by reference

fixed the issue. Will look into that further On the code below, do I need to create an instance of my list when I use the constructor in ClassWithList? , You have to do some simple corrections (explanations in comments):
code :
class AbstClass;
class ObjClass : public AbstClass; // << You need to derive as public

class ClassWithList
{
    std::list<const AbstClass *> absts;
public:
    ClassWithList(); // You don't need new list, it will be allocated 
                     // already correctly at construction
    void addToList(const AbstClass& obj)
    {
        absts.insert(&obj); // << pass the address
     // ^^^^^ The member is named absts
    }
};

hope this fix your issue You are not storing bullets in these lists, but pointers to bullets, so no destructor will be called. The objects can be safely removed from all lists, but you will need to call delete yourself.

will be helpful for those in need Node * &foo is a reference to a Node *
So when you call it with
code :
AddNode(A, 123, 99.87);

will be helpful for those in need This is maybe not as much an answer as it is a general explanation of pointers, references and reference semantics.
A function is said to have reference semantics if it can change the argument objects that are passed to it. For example, the following swap function has reference semantics if it exchanges the values:
code :
int x = 4;
int y = 8;

swap(x, y);

assert(x == 8 && y == 4);
void swap(int & a, int & b) { int t = a; a = b; b = t; }
void c_swap(int * p, int * q) { int t = *p; *p = *q; *q = t; }

may help you . I have to give all the credit to @Craig here. VBA and VB.NET have indeed different matrix addressing logics (column major vs. row major), so I had to transpose all the 2D arrays, without swapping FFThetaPoints and FFPhiPoints.
It is worth mentioning that I tried using the Excel.Application Worksheetfunction.Transpose method, which didn't work as expected. So I had to write my own piece of code to transpose the matrices.
