Question

I’m trying to create a dynamic array of objects, similar to ArrayLists in Java. I’m new at C++ and can’t get it to work.

class Album{

private:

public:
    void addPhoto(Photo p){

    }

};

What should my private datamember look like and how do I add p to it? And do I need a pointer for some reason?

Answer 1

The functionality you look for already exits in the stl collection classes and and with out knowing you application it would be had to tell you weather you needed a pointer or not.

The basic layout of you underlying container could be something like this.

class Album{    

public:
    void addPhoto(Photo p){
         Photos.push_back(p); 
    }
private:
    std::vector<Photo> Photos; 

};
