Design patterns are often misunderstood. They are really a way for experienced users to have shorthand for describing common situations. You don't need to worry about them too much while you are learning C++.

You will hear discording opinions about design patterns, in the programming community at large.

In my opinion, it is sure that there are abstractions that patterns encapsulate that are really useful (factory, singleton, delegate, etc.). I use patterns a lot, but I myself am sometime puzzled by the apparent lack of depth or level of insight that you get by reading a pattern description. This is also in tune with the proliferation of design patterns that specialize for any kind of things.

When the design hey are useful, they are a very good means of communication and certainly they guide you through the process of designing or defining the architecture of your app. They are useful both for small project and for large ones, and they can be applied at different granularity levels.

Patters are a generic concept and all programming languages support them. Anyway, if you work in C++, a book focusing on it is best, because you will get the pattern adapted to the characteristics of the language.

In my opinion, the really fundamental book about design patterns are:

Most of the design pattern are common to all object oriented languages.

blocks|key|2821240|text|对我来说，设计模式只不过是缩短程序员之间交流时间的抽象。您可以找到一个描述程序设计的模式的名称，而不是表达如何设计程序的复杂概念。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2821241|例如，TPM说“我们应该在这里使用单例”，而你解释说“我们应该在这里使用类的一个实例”。|2821242|模式对学习很有用，但是人们可以在不知道任何模式的情况下进行编程，但却经常使用它们。|2821243|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

For me design patterns are nothing but abstractions that shorten communication time between programmers. Instead of expressing a complex idea of how your program is designed, you can probably find a name of a pattern that describes the design of your program. 

E.g. TPM says "We should use singleton here", and you interpret "We should use one instance of the class here". 

Patterns are useful to learn, but one can program without knowing any patterns, yet using them a lot.

blocks|key|4611325|text|我认为设计模式是从经验中获得的智慧的集合，特别是解决代码的灵活性和可维护性问题。例如:通过使用外观，我们可以在不更改使用外观的代码的情况下更改实现。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4611326|我认为公平地说，所有的编程语言都有需要捕捉的智慧，某种设计模式将是有用的。C/C%2B%2B/Java/C#传统语言似乎提供了一种特别丰富的似乎挖掘智慧的方法。C%2B%2B相当粗糙，确实受益于一些关键的设计模式。|4611327|一些人认为设计模式是弥补语言缺陷的一种方式，这意味着“更好的”语言可能需要更少的模式。我的感觉是，在所有情况下，我们都可以从有经验的人那里学到一些东西，而模式可以帮助我们将他们的智慧编成法典。|4611328|编辑补充:穆尼什提出的有趣的观点，最好先做一点重新设计？通过编写一些没有显式使用模式的真实代码，您很可能会开始对所编写的内容感到不满意……当我改变这一切时，我需要改变这一切，有没有更好的方法来写这篇文章呢？这可能会驱使您真正地need+patterns，从而激励您的学习。|offset|length|style|BOLD|4611329|如果你有足够的时间来学习这种方法，那么我想你可能会从中受益。|4611330|entityMap^0|0|0|0|35|4|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|Q|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|R|8|@]|9|@]|A|$]]|$1|F|3|G|5|6|7|S|8|@$H|T|I|U|J|K]]|9|@]|A|$]]|$1|L|3|M|5|6|7|V|8|@]|9|@]|A|$]]|$1|N|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|O|$]]

I see design patterns as collections of wisdom gained by experience, particularly addressing issues of flexibility and maintainability of code. For example: by using a facade we can change implementations without changing the code that uses the facade.

I think it's fair to say that all programming languages have wisdom to be captured, and design patterns of some sort will be useful. The C/C++/Java/C# heritage languages seem to offer a particularly rich seem to be mined for wisdom. C++ being quite gnarly really does benefit from some key design patterns. 

Some folk see Design Patterns as a way of patching over language deficiencies, that would imply that "better" langauges might need fewer patterns. My feeling is that in all cases we have something to learn from experienced folks and Patterns help us codify their wisdom.

Edited to add: Interesting point made by Munish, it is best to do a little reinvention first? By writing some real code without explicit use of Patterns you may well start to feel dissatisfied with what you write ... when I change this, I need to change all that, is there a better way to write this? ... this may drive you to really need patterns and hence motivate your study.

If you have the luxury of time to learn this way then I think you'll probably benefit.

blocks|key|2821226|text|设计模式是project.These设计阶段常见问题的解决方案，模式提供了我们可以独立于编程language.For使用的解决方案，例如，单例设计模式，它确保class.Now只有一个实例，在许多情况下可能会出现这种情况，required.You可以使用这些模式的解决方案并在您的代码中使用。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2821227|它们在软件开发.Put中提供了可重用性，简单地说，设计模式可以帮助设计人员更快地获得正确的设计。|2821228|要想更好地理解，可以参考Design+Patterns:+Elements+of+Reusable+Object-Oriented+Software|2821229|entityMap|0|LINK|mutability|MUTABLE|url|https://rads.stackoverflow.com/amzn/click/com/0201633612^0|1X|6|0|F|W|0|C|1Q|0|0^^$0|@$1|2|3|4|5|6|7|R|8|@$9|S|A|T|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|U|8|@$9|V|A|W|B|C]]|D|@]|E|$]]|$1|H|3|I|5|6|7|X|8|@]|D|@$9|Y|A|Z|1|10]]|E|$]]|$1|J|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|K|$L|$5|M|N|O|E|$P|Q]]]]

Design patterns are solutions to commonly occuring problems in Design phase of a project.These patterns provide the solutions which we can use independent of programming language.For e.g. there is Singleton design pattern which ensures that there is only one instance of a class.Now there are numerous occaions on which this may be required.You can use the solution of these pattern and use in your code.

They provide the re usability in Software development .Put simply, design patterns
help a designer get a design right faster.

I am learning C++
I don't know much about this stuff except the fact that programming design pattern is neccesary when actually working in large projects.I hope its correct to some extent.

Is this common to all object oriented languages or do I need to look specifically into 
C++ design patterns.

Also How does it helps you.Is this realy important to learn as a C++ programmer.

Please suggest

我正在学习C++，除了编程设计模式在大型项目中是必不可少的这一事实之外，我对这些东西知之甚少，我希望它在某种程度上是正确的。这对所有面向对象语言来说都是通用的，还是我需要专门研究一下C++设计模式。另外，作为一名C++程序员，它如何帮助you.Is学习这一点非常重要。请给出建议
