C and object?

LearningProgramWhen do we start to have the object concept? Start with learning C ++ and hear the word object-oriented (OOP ). I am afraid that many people have come up with the definition of "object"-I remember it is probably "abstraction of things with common attributes"-so many people think they "understand" object-oriented, some people even know that in programming, objects are encapsulated by classes, so they often stick to "Object-Oriented Programming" and become a high-level language programmer.

After talking about this, you probably heard what I was suggesting. Yes, as you are worried about, if you understand "object" and "class" as I said just now, it can be said that you are totally misled by the descriptive language called "plump" by the textbook author-even some people are intimidated by this obscure definition and give up being a programmer.

Give another suggestion: Machine-levelCode(Or machine/system), that is, the combination of some 1/0, does not know what the "class" is, the so-called C ++ class (I suppose you know C ++) three-level protection for data members (private/shared/protected) is only implemented during compilation. In other words, if a perverted compiler author ignores these three keywords completely, therefore, the so-called "encapsulation" does not have any protection effect.

Back to the "object" discussion, what is "object" now? Objects are a combination of programs and data. C ++ is known as "Object-Oriented", that is, it provides support in syntax. If you have enough knowledge about the relationship between data and operations in your program, c can also be used to implement "objects". However, if you do not know the relationship, that is, using C ++ and a more advanced "Object-Oriented" language, how can you "abstract" and define a reasonable "class?
