C + + templates
Templates are the basis of generic programming, which is to write code in a way that is independent of any particular type.

A template is a blueprint or formula for creating a generic class or function. Storage converters, such as iterators and algorithms, are examples of generic programming that use the concept of templates.

Each container has a single definition, such as vectors, we can define many different types of vectors, such as vector <int> or vector <string>.

You can use templates to define functions and classes, and then let's take a look at how to use them.
