Many original ideas of OOP are derived from the Simula language.Being bettered and standardized on basis of the Simula language,OOP has evolved a lot. We can say that development of the idea of OOP and OOPL are almost synchronously and each promotes the other. Different from functional-programming and logic-programming which represent the actual calculational models similar to computers architecture, OOP hardly brings in precise mathematical descriptions,but tends to create an objective models which can reflect the relationship among entities in practical field.Essentially,It is a calculational model which is more closer to man's cognitive process. So we have the question that what is OOP on earth? In OOP, object,known as calculation aim has its individual name,status,interface for receiving messages from external objects. In an Object Model, creating of a new object,destruction of exsiting objects,sending messages,responding messages, all these constitute the fundamentality of OOP. 如下 请过目：
