What is template inheritance in C++?

Template inheritance in C++ allows a class template to inherit from another class template, enabling code reuse and flexibility.

Can you give me an example of template inheritance?

Sure! Here's a simple example:

template <typename T>
class Base {
public:
    void show() { std::cout << "Base class" << std::endl; }
};

template <typename T>
class Derived : public Base<T> {
public:
    void display() { std::cout << "Derived class" << std::endl; }
};

In this example, Derived inherits from Base, allowing it to use its methods.

What are the benefits of using template inheritance?

The benefits include code reusability, type safety, and the ability to create more generic and flexible code structures.

Are there any drawbacks to template inheritance?

Yes, some drawbacks include increased complexity, longer compile times, and potential difficulties in debugging due to template instantiation.
