We tend to use process-oriented thinking to think, C language is a process-oriented language, as we get started programming language is very suitable, although the process-oriented language is more efficient, but it is more cumbersome to write a large program, at this time in order to solve this problem, We put forward the programming idea of object-oriented programming;

Three main features of object-oriented: encapsulation, inheritance, polymorphism

Encapsulates a set of objects with the same characteristics and behavior into a class

Declaration and definition of a class

Instantiation of a class

Inherited
