Dynamic Objects!

[commander40]

Hi,
How do I store dynamically generated lists in to files?
This is my class ...

#include<iostream>
#include<string>

using namespace std;

class CMp3
{
	struct CElement
	{
		char SongName[30];
		char SongInterpret[30];
		double SongLength;
		CElement *next;
	};

	CElement *list;
public:
	void PushFront(const char name[30],const char interpret[30],double length);
	void PrintList();
	void PushBack(const char name[30],const char interpret[30],double length);
	void SaveInFile();
	void LoadFromFile();
	void PushBack();
	CMp3():list(NULL)
	{
	}
	~CMp3();
};

And the objects are being created like this...

void CMp3::PushFront(const char name[],const char interpret[],double length)
{
	CElement *elem = new CElement;
	elem->next = list;
	list = elem;
	
	strcpy_s(list->SongName,name);
	strcpy_s(list->SongInterpret,interpret);
	list->SongLength = length;
	
}

Thanks a lot!

Use std::string and std::list.
As for the serialization part, see here:

Agree that there is already code and classes for this. But in order to serialize into a stream your current code, you could:

void SerializeList(const CElement *list, ostream &os)
{
    const CElement *current = list;
    while (current)
    {
        os << current->SongName << current->SongInterpret << current->SongLength;
        current = current->next;
    }
}

That probably works OK.
