In C++ you can create a templated class for generic trees that work with arbitrary data types. You may need to implement optimized trees for some use cases where performance is critical, but when you only need a random tree somewhere, it’s great to have a generic templated tree class available.

One of the most common data structures in computer science and programming is a tree. Trees are an abstract data type for all kinds of hierarchical data like file systems, parse trees, domain object models (HTML, XML), binary search trees, and many more.

Yet, there is no tree type in the C++ standard library.

Luckily, it’s not that difficult to create a tree data structure yourself. After creating many different trees for several projects over the years, I finally implemented a proper tree class with templates to make it work with arbitrary types.
