How can I create custom containers using STL in C++?

To create custom containers in C++, you can start by inheriting from existing STL containers or implementing your own class. What specific features do you want in your custom container?

I want it to support dynamic resizing and iteration.

You can achieve dynamic resizing by managing a dynamic array internally and implementing methods for adding and removing elements. For iteration, you can define an iterator class that allows traversal of your container.

Can you show me a simple example?

Sure! Here's a basic example of a dynamic array-based container:

template <typename T>
class CustomContainer {
private:
    T* data;
    size_t size;
    size_t capacity;
public:
    CustomContainer() : size(0), capacity(10) {
        data = new T[capacity];
    }
    // Add methods for adding, removing, and iterating...
};

This initializes a container with a capacity of 10.

What about memory management?

Good question! You should implement a destructor to free the allocated memory and consider using smart pointers for better memory management.
