Visibility Modes :
An important feature of Inheritance is to know which member of the base class will be acquired by the derived class. This is done by using visibility modes. The accessibility of base class by the derived class is controlled by visibility modes. The three visibility modes are private, protected and public. The default visibility mode is private. Though visibility modes and access specifiers look similar, the main difference between them is Access specifiers control the accessibility of the members with in the class where as visibility modes control the access of inherited members with in the class.
Private Visibility Mode :
When a base class is inherited with private visibility mode the public and protected members of the base class become 'private' members of the derived class.
Protected Visibility Mode:
When a base class is inherited with protected visibility mode the protected and public members of the base class become 'protected members ' of the derived class.
Public Visibility Mode :
When a base class is inherited with public visibility mode, the protected members of the base class will be inherited as protected members of the derived class and the public members of the base class will be inherited as public members of the derived class.

Types of Inheritance
There are different types of inheritance viz., Single inheritance, Multiple inheritance, Multilevel inheritance, hybrid inheritance and hierarchical inheritance.
1. Single Inheritance: When a derived class inherits only from one base class, it is known as single inheritance.
2. Multiple Inheritance: When a derived class inherits from multiple base classes it is known as multiple inheritance.
3. Hierarchical inheritance: When more than one derived classes are created from a single base class, it is known as Hierarchical inheritance.
4. Multilevel Inheritance: The transitive nature of inheritance is itself reflected by this form of inheritance. When a class is derived from a class which is a derived class - then it is referred to as multilevel inheritance.
5. Hybrid inheritance: When there is a combination of more than one type of inheritance, it is known as hybrid inheritance. Hence, it may be a combination of Multilevel and Multiple inheritance or Hierarchical and Multilevel inheritance or Hierarchical, Multilevel and Multiple inheritance.
