The Viusal C++ brief introduction The object-oriented basic concept thinking mode decided solves the question way, the traditional software development uses from the top thought instruction programming, soon the goal divides into certain subtargets, the subtarget further divides again, can program until the goal the realization. The object-oriented technology brings the enormous change for the software design domain, it carries on the procedure development using the software object, the so-called object is contains the data and to the data manipulation code entity, or said is joins some in the traditional construction of data to be called the member function the process, thus entrusts with the object by the movement. But in the programming, the object has with the real world some kind of corresponding relations, we are precisely use this kind of relations to carry on the decomposition to the question. Looked from the program language angle that, in an object the code and (or) the data may be this object private, cannot by the object outside part direct visit. Thus the object provided one kind of high-level protection to prevent the procedure has nothing to do with the part wrong revision or has used wrongly the object private part. When attempts from the object to receive directly which protects internal data carries on the revision, by procedure rejection, only then the foreign service function material which provides through the object can to its internal data carry on the essential processing, thus has guaranteed the data processing validity. Says from this significance, is called this kind of code and the data relation “the seal”. In other words, the seal is protects the object seal, is ability which hides the internal detail. Entrusts with heavy responsibility the aspect in the emphasis software module, object-oriented technical and the standard industrial design rule has more similarities. In the object-oriented language, the kind is found
