Curiously Recurring Template Pattern

Curiously Recurring Template Pattern, or CRTP for short, is essentially a C++ idiom. It is also known as Static Polymorphism or Simulated polymorphism.

Here's the differences between (actual) Dynamic polymorphism and Static polymorphism (CRTP):

Requirements for dynamic polymorphism:

1. Is-a relationship between base and derived class.
2. Base class defines a 'generic' algorithm that is used by derived class.
3. The 'generic' algorithm is customized by the derived class.

Requirements for static polymorphism:

1. 'Is-a' relationship between base and derived class.
2. Base class defines a 'generic' algorithm that is used by derived class.
3. The 'generic' algorithm is customized by the derived class.
4. This method is pure virtual. The derived method implements it.

Benefits

• CRTP is simulating dynamic...
