What is template inheritance and how does it work in different programming languages?

Template inheritance is a programming concept where templates can inherit properties and methods from other templates. In languages like C++, templates allow for generic programming, while in languages like Python, template inheritance is often seen in frameworks like Jinja2 for rendering HTML.

Can you give me an example of template inheritance in Python?

Sure! In Python, using Jinja2, you can create a base template with common layout elements and then extend it in child templates. For example, a base template might define a header and footer, while a child template can fill in the main content.

How does this differ in C++?

In C++, template inheritance allows a class template to inherit from another class template. This enables the derived template to use the base template's functionality while adding or modifying its own. It's more about type safety and code reuse compared to the rendering aspect in Python.

Are there any other languages that use template inheritance?

Yes, many languages like Java and C# use similar concepts, often referred to as generics. They allow for type-safe data structures and methods, promoting code reuse and flexibility.
