What is a C++ instantiation?
Instantiation is when a new instance of the class is created (an object). In C++ when an class is instantiated memory is allocated for the object and the classes constructor is run. In C++ we can instantiate objects in two ways, on the stack as a variable declaration, or on the heap with the new keyword.

The definition created from a template instantiation to handle a specific set of template arguments is called a specialization.
