What is template specialization in C++?

What is template specialization in C++?

Template specialization allows you to define a specific implementation of a template for a particular type.

Can you give me an example of template specialization?

Sure! Here's a simple example:

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

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

What happens if I don't use specialization?

If you don't use specialization, the generic template will be used for all types, which may not provide the desired behavior for specific types.

Are there any performance benefits to using template specialization?

Yes, template specialization can lead to performance improvements by allowing optimizations specific to certain types.
