public inheritance

If you make class D inherit Class B in the form of public, you will tell the C ++ compiler that every object of the D type is also an object of the B type, and vice versa. B is more general than D, and D is more special than B. If any function is

Public inheritance means a "is-a" relationship. It means: If B inherits from a in public form, then the B-type object is definitely a object of a, and vice versa. A is an abstraction of B, and B is a special case of a. B can be used in any place

Three basic features of object-orientedThe three basic characteristics of object-oriented are encapsulation, inheritance, polymorphism. The encapsulation can hide the implementation details and make the code modular; Inheritance can extend existing

# Include using namespace STD; Class A {public: int A ;}; // to access a, the public must inherit a Class B: Public A {public: int C; int B ;}; int main () {B * B = new B (); B-> C = 3; B-> A = 1; A * A = B; if (a-> A = 1) {B * c = (B *) A; cout C

When a subclass inherits a parent class, it can inherit the parent class in public, private, and protected ways, each of which differs in the following ways: 1) Public inheritance mode All public members in the base class are public properties in

  Given a hierarchy (inheritance system), one class student is inherited from a class person public. When it is necessary to call a function successfully, students needs to be implicitly transformed to persons, it demonstrates this to the compiler.

Look at the following example: #include using namespace Std;Class AClass{Publicint m_anum;PublicAClass () {m_anum = 0;}~aclass () {}int Getanum () {return m_anum;}};Class Bclass:public AClass{Publicint m_bnum;PublicBclass () {m_bnum = 1;}~bclass ()

What is private inheritance? When I was studying at school, I had never studied such a thing carefully. Later, I used the boost library in my work to learn about it. If we say that most inheritance protection is for language integrity, private

Three inheritance methods in class design and three inheritance methods are designed.Zookeeper By inheritance, a new class can be derived from an existing class, and the derived class inherits the features of the base class, including methods. Just
