return values. With regard to article 1st, Bill Wagner mentioned in the terms that "reference types impose a burden on the garbage collector" appears to be a correct judgment. However, due to the box/Unbox effect, in some cases, the value type has brought more burden to the garbage collector. For example, you can place some value types in a collection and then perform read/write operations on them frequently. If this happens, I think it is not a better way to "discard the structure and adopt

Item 19: regard class design as Type Design) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ In C ++, just like other object-oriented programming languages (Object-Oriented Programming Language), a new type is defined by defining a new class (class ). As a C ++ developer, you spend a lot of time increasing your type system. This means that you are not only a class designer, but alsoTypeDesigner

Item 45: Use member function templates (member function template) to accept "all compatible types" ("all compatible types ") By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Smart pointers(Smart pointer) is a objects that acts like a pointer but adds functionality not provided by the pointer. For example, item 13 describes how the standard auto_ptr and tr1: shared_ptr are used to automatically d

Item 13: use objects to manage resources By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Suppose we work with a library of simulated investments (such as stocks and bonds), and various investment forms are inherited from a root class (root class) Investment: Class investment {...}; // root class of hierarchy// Investment Types Let us further assume that this library provides us with the method of

Item 39: exercise caution when using private inheritance (private inheritance) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Item 32 discusses how C ++ regards public inheritance (Public inheritance) as an is-a relation. Given a hierarchy (inheritance system), one class student inherits from a class person public. To successfully call a function, students must be implicitly transformed to perso

Appendix A. BeyondValid C ++ By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Valid C ++Covers the general guidelines that I think are most important to the current C ++ programmers, but if you are interested in improving your effectiveness in more aspects, I recommend that you study other C ++ books,More effective tive C ++AndValid STL. More effective tive C ++Covers other programming guideline

Chapter 5. Implementation By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ To a large extent, you can provide appropriate definitions for your classes (and class templates (class templates) and your functions (and function templates (function templates )) providing appropriate declarations is a key part of the battle. As long as you get the correct results, the corresponding implementation is stra

Item 33: Avoid overwriting "the name obtained by inheritance" By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Shakespeare has a saying about the name. "What's in a name? "He asked," A rose by any other name wocould smell as sweet. "(in the second scene of" Romeo and Juliette ", Mr. Zhu shenghao translated:" The name is meaningless. We call it the Rose Flower. If we change the name, the fragrance

Item 26: variable definitions (variable definition) is postponed whenever possible) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ If you define a variable with a constructor (constructor) or destructor (destructor) type, when the control process reaches the variable definition, you will be subject to the construction cost, when the variable leaves the scope, you will be responsible for analyzin

Item 34: differentiate inheritance of Interface (interface inheritance) and inheritance of implementation (implement inheritance) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ (Public) inheritance is a simple and easy-to-understand concept. Once it is closely examined, it will prove that it is composed of two independent parts: inheritance of function interfaces (Inheritance of function interfa

Item 37: Never redefine the inherited default parameter value of a function (the default parameter value obtained through inheritance) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ We started to simplify this topic. Only two functions can be inherited by you: Virtual and non-virtual ). However, redefining an inherited non-virtual function (a non-virtual function derived from inheritance) is alw

Item 25: consider supporting a non-throwing swap (without throwing an exception swap) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Swap is an interesting function. It was first introduced as a component of STL, and later became the pillar of exception-safe programming (abnormal security programming) (see item 29) and General mechanism to suppress the possibility of self-assignment (see item

Item 12: Copy all parts of an object) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ In the well-designed object-oriented systems (object-oriented system), the internal component of the object is encapsulated. There are only two objects (object) Copying functions: it is called copy constructor (copy constructor) and copy assignment operator (copy assignment operator ). They are collectively re

Item 7: declare Destructors (destructor) as virtual in polymorphic base classes (polymorphism base class) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ There are many ways to get the time, so it is necessary to establish a timekeeper base class (base class), and create Derived classes (derived class) for different timing methods ): Class timekeeper {Public:Timekeeper ();~ Timekeeper ();...}; C

Chapter 2. constructors, Destructors, and assignment operators) By Scott Meyers Translator: fatalerror99 (itepub's nirvana) Release: http://blog.csdn.net/fatalerror99/ Almost every class you write has one or more constructors, one destructor, and one copy assignment operator ). Don't be surprised. They are just like your bread. They control basic operations, such as creating a new object and ensuring that it has been initialized, eliminate an object

than code segment 1. In these two instances, "1", "2", and "3" are called odd numbers, while "Sleep", "power_off", and "power_on" are fixed values. There are three methods for defining fixed values in C ++: # define, const, and enum.Scott Meyers, author of effect c ++, once suggested that const should be used to replace # define with Const. This sentence is not without reason. On the other hand, # define and const can be used in many places.For examp
