If I have the following
template<class T> print_all(vector<T> const & collection);
What would you call T in context of the declaration? i.e. Would you say that T is the argument for vector const & collection? i.e It satisfies a vector as the type is closed?
Keen to find out what the actual terminology is.

Templates are a feature of the C++ programming language that allows functions and classes to operate with generic types. This allows a function or class to work on many different data types without being rewritten for each one.
C++ template is also known as generic functions or classes which is a very powerful feature in C++. A keyword “template” in c++ is used for the template's syntax and angled bracket in a parameter (t), which defines the data type variable.
There are two types of templates in C++, function templates and class templates.
A template is a simple yet very powerful tool in C++. The simple idea is to pass data type as a parameter so that we don't need to write the same code for different data types. For example, a software company may need to sort() for different data types.
T is a template parameter of the function template print_all, which is used as a template argument for the class template vector.
