Part I. Explores the techniques necessary to transform a structured computer language into an object-oriented language. Object-oriented principles; Object-oriented syntax; Importance of coding style and code organizations; Development of a toolbox of classes that a software engineer could have at his...
C# is an object-oriented programming language. The four basic principles of object-oriented programming are:Abstraction Modeling the relevant attributes and interactions of entities as classes to define an abstract representation of a system. Encapsulation Hiding the internal state and functionality of an...
The added method isprotected, which means that it can be called only from derived classes. That declaration prevents other clients from calling the method. It's alsovirtualso that derived classes can change the behavior. The return type is aTransaction?. The?annotation indicates that the method...

OOPC是指OOP(Object-Oriented Programming)与C语言的结合,它是一个面向对象C语言编程框架。它是一套C语言的宏,定义了OOP概念的关键字,借助于这一套宏,实现面向对象的特性,如类、对象、继承、接口、多态、消息等。 C++对于大型软件架构的良好可控性,和对以后程序员维护代码时良好的可读性;然而就目前来说,在嵌入式...

C语言自带一些数据类型,包括char,int,double,指针,union和struct。 char,int表示一定范围的整数值,但它表现行为确极大程度依赖硬件实现,比如在32位和64位机器,int的范围却是不一样的;其次double代表小数,但它表现的行为确和数学中的实数不一样,类似以下情况: ...
