<Effective C++>读书摘要--Inheritance and Object-Oriented Design<一>

Go hastypes and valuesrather than classes and objects. So can a language without classes or objects be object-oriented? While Go may not fit the typical mold of an OOP language, it does  provide many of the same features, albeit in a slightly differe

1.除了内存资源以外,Other common resources include file descriptors, mutex locks, fonts and brushes in graphical user interfaces (GUIs), database connections, and network sockets. Regardless of the resource, it's important that it be released when you're fini

<Item 22> Declare data members private 1.使数据成员private,保持了语法的一致性,client不会为访问一个数据成员是否需要使用括号进行函数调度,还是不使用括号直接访问成员而纠结. 2.使数据成员private,if you use functions to get or set its value, you can implement no access, read-only access, and read-write access. Heck

一直在用STL,认为对STL也有一些理解,比如比较函数怎么写,什么情况下用什么容器效率高,但是当你读过Effective STL之后才知道这远远不够,之前的代码还有很多可以优化的空间,下面我会罗列一些映像比较深的点,比较偏向代码因为这样可以方便以后的调用.这里是到Item29,余下的留下次看. 1) 检查容器是否为空 if(c.empty()){}   better than if(c.size()==0){} 2)如果能用批量操作函数就不要用循环来做 批量操作可以提高效率,要有能用批处理尽量批

1.The initial motivation for C++ templates was straightforward: to make it possible to create type-safe containers like vector, list, and map. Ultimately, it was discovered that the C++ template mechanism is itself Turing-complete: it can be used to

<Item 9> Never call virtual functions during construction or destruction 1.you shouldn't call virtual functions during construction or destruction, because the calls won't do what you think, and if they did, you'd still be unhappy. If you're a recov

<Item 20> Prefer pass-by-reference-to-const to pass-by-value 1.By default, C++ passes objects to and from functions by value (a characteristic it inherits from C). Unless you specify otherwise, function parameters are initialized with copies of the

OOD的流程: 需求分析-->系统/程序设计-->实现这个设计-->测试 Class Design 1. Identify classes for the system. 2. Describe attributes and methods in each class. 3. Establish relationships among classes. 4. Create classes. Identity classes and objects A fundamental part o

Introduction This tutorial will help you to understand about Java OOP'S concepts with examples. Let's discuss about what are the features of Object Oriented Programming. Writing object-oriented programs involves creating classes, creating objects fro
