How do I implement template specialization in C++?

Template specialization allows you to define different behaviors for specific types in C++. You can use full or partial specialization.

Can you show me an example of full specialization?

Sure! Here's a simple example:

template <typename T>
class MyClass {
public:
    void display() { std::cout << "Generic version"; }
};

// Full specialization for int
template <> 
class MyClass<int> {
public:
    void display() { std::cout << "Specialized version for int"; }
};

In this example, MyClass<int> has a specialized display method.

What about partial specialization?

Partial specialization allows you to specialize a template based on some of its template parameters. For example:

template <typename T, typename U>
class MyClass {
public:
    void display() { std::cout << "Generic version"; }
};

// Partial specialization for T and int
template <typename T>
class MyClass<T, int> {
public:
    void display() { std::cout << "Specialized version for T and int"; }
};

Here, MyClass<T, int> is a partial specialization.
