First of all, isn't this article really a lot of pitfalls for @ left ear mouse C ++? I just explained some of my thoughts on language selection from the perspective of my understanding.
The debate on C and C ++ has been around for a long time. Since Linus attacked C ++ as a horrible language, it never stops. For me, I do not have enough knowledge of C ++, so I have no ability to compare it from the perspective of language design (I also tried to learn C ++ at the beginning, I used C ++, but later I found that I had a hard time learning and had a bad time, so I gave up ). so I try to avoid making mistakes in this regard.
It is true that C ++ has introduced many new things. As @ said, it is designed to solve some problems, but is the problem necessary?
In my opinion, a language or tool is a tool. It exists so that we can use it to solve the problem. from this point of view, the biggest advantage of a language should be that it is easy to get started and can be quickly mastered, so that the learners will not put the cart before the horse, and they will spend a lot of energy on the use of "Tools.
Of course, there is also a cloud in old saying: "We must sharpen our tools to do good deeds." However, compared with C ++, C ++ has not extended more applicable scenarios nor improved its performance, not to mention how much development efficiency is improved. Of course, from OO, the design concept can more or less affect users and improve the maintainability of code. however, this is not necessary, because there are too many successful and highly maintainability C Projects, Linux, Unix, Apache, PHP .......
I have some experience in language design. When we design and develop PHP, the most careful thing is the addition of New syntaxes. This process is almost harsh. It is a new language feature, it often indicates incompatibility, more misuse, and more learning costs. so we instinctively reject some New syntaxes. this is also a simple pursuit.
Compared with C, C ++ provides more New syntaxes and new language features. That is to say, it requires more learning time and higher learning costs. for example, let's take a look at how thick C ++ primer is. It's not enough to read it, because there are still many details that you may misuse, so there are: "negative tive C ++ ", "More than tive C ++", oh, there are STL, "More than tive STL" and so on. are you willing to spend so much energy learning a language?
If you think that learning a deep language can satisfy your own IQ superiority, I have nothing to say, but I still want to kindly remind you that even if you spent more than half a year, after learning this, you still can't do anything, because the language still needs to be combined with the actual situation, to be actually used, there is still a lot of knowledge waiting for you: "Advanced Programming in the UNIX Environment", "Unix Network Programming". For Windows, there will be more books to read...
So now, do you still think that you have so much time to learn all this? If you really insist that you have time, well, let me remind you that you have learned a lot that you cannot understand at this time. because you have not encountered some experience in design patterns when actually solving the problem, you do not understand those design patterns or some seemingly useless functions. look, what is the contradiction? learning advanced languages requires real project experience, and real project experience requires you to learn a language before learning it ....
From this perspective, I think PHP and C are very similar. I bought only one book for learning PHP, but I didn't finish reading it because I learned a tutorials, I found that I have learned how to solve the current needs... For me, a PHP manual is enough ....
Some people may ask how to develop a simple language after learning it so easily?
This may be the case for human nature. I think it will be difficult to master complicated things. However, they forget that I just thought that language is just what you learned to solve your actual problems, by turning your ideas into practical tools, your growth should be the growth of your experience in solving problems while using them, rather than the growth of your language skills.
When you have been studying books for three years in order to be proficient in a language, and finally become proficient one day, you may find that this language is no longer popular... What do you think? (When I wrote this section, my head showed that Wang Chongyang was out of service in the east to the west)
Therefore, do not put the last word upside down. Choose what you will use (learn one that is easy to learn) and start solving practical problems as soon as possible!

It is my opinion just now, language is just a tool you learn to solve your actual problems and turn your ideas into practical tools. Your growth should be in the process of using them to solve problems, the growth of experience in solving problems, rather than the growth in the use of language skills.

- , Liu Zhiqiang writes: From the Perspective of solving the problem, C and C ++ may be slightly different. Although C ++ provides enough features for us to use, but citself is enough. Then, for specific problems, different languages solve different problems. For example, the efficiency advantages of C and C ++ are beyond the reach of PHP, Perl, and Python. I used to use PHP to implement an algorithm that was implemented using C ++ in the current project. The efficiency was more than 10 times worse. However, I also used PHP to implement a cgi web system that was implemented using C ++ in the project at that time, with almost the same efficiency, in addition, the advantage of PHP's rapid development and ease of maintenance in this respect is that C ++ is far from perfect. Of course, I also used Bash to implement a fast sorting or more complex decision tree classification algorithm. Efficiency is terrible. However, when Bash is used for general tasks in Linux, no other language has its development efficiency or maintenance advantages. This is the case. The language used depends on the problem you want to solve.

- , Liqiang427 writes. Here are the performance constraints. What do you do if your python, perl, and php cannot be reached? You have to use C ++ to develop simple images and websites. You have to defend against this development cost, which is several times the development cost in other languages, it is also your problem to get the same result as other development languages... In my opinion, whether to study C ++ depends on whether you can use it or not, and whether you want to work in the future. However, people who study C ++ often have some inexplicable superiority...
- , Wclssdn writes: language used last year .. AAuto. similar to VB. drag it. drag it, and write the program. at that time, I used a few days to get to know this language, and then I wrote a small tool that I needed at that time .. however, when I want to study it in depth, I find that the language does not have any rules... there are various usages... no standard. some places are like this, some places are like this .. it's hard to learn .. I gave up .. I don't know what's going on later .. my gadgets were killed, and they were killed relentlessly -_-!!!

For PHP, he is a quick start, but he is proficient in a difficult language. His function is very free and he wants to achieve a result, PHP functions can be implemented in multiple ways, but which method is more efficient can only be used for actual testing or on demand .. At least I have been working for several years and PHP functions are useless... So it is king to keep the PHP manual. You have always been using yaf... I have developed many projects.

If you only use php, try another language?

As the father of c ++, he is familiar with the comparison between languages, I think we should be more serious. Don't mislead others?

I am very pragmatic, it will not be used rashly, but ++ is definitely useful.
