Inheritance provides an opportunity to reuse the code functionality and fast implementation time. The members of the class can be Public, Private or Protected. Syntax:class DerivedClass : AccessSpecifier BaseClass
The default access specifier is Private. Inheritance helps user to create a new class (derived class) from a existing class (base class).
