A concrete class is a complete type, as opposed to an abstract class which is an incomplete type.
class A {
public:
virtual void f () = 0; // pure-virtual; class A is abstract
// ...
};
class B : public A {
public:
void f () override; // overrides A::f(); class B is concrete
};
class C {
// no pure-virtual methods; C is a concrete type
// ...
};
Template classes are generic types. We usually evolve a generic type from a concrete type rather than write a template class from scratch, a technique known as lifting. The concrete type provides us with the complete implementation which is useful for testing and debugging purposes. When the concrete class is fully-implemented and error-free, we can generalise to produce the generic type.
