I saw on the Internet before a lot of news about c + + 20, I feel quite confused, I think I learn c + + 11 in 2020 will be useless or c + + 11 is the basis of the c + + 20 or c + + 20 directly out of c + + 11?
Can someone explain use c + + 11 in 2020 is also big?

CodePudding user response:

Big, big, new standards generally five to ten years are not popular

CodePudding user response:

C + + 11 and 20 c + + is not completely incompatible,,,,

Even if a new version of the compiler may also have a small amount of c + + 11 features not fully support, refer to: https://en.cppreference.com/w/cpp/compiler%20support

First of all, it must be useful; The second revised on the basis of the c + + 20 is in c + + 11, specific as follows:
C + + 11,14,17,20 these are just a version of the standard c + +, is like a book, every once in a while will be revised, may add some content or remove some of the content, but rarely remove content c + + standard, such as

The standard c + + 11 has added a lot of things, the equivalent of a big version; 14,17,20 increase are small, c + + 11 I am from that is commonly used in peacetime work, bind, thread, mutex, lock_guard, tuple, strong enumeration, etc., not all the new features will be used, 14,17,20 additional content is rarely used or it was basically useless to,
C + + standard content so much, no one will be, as long as you grasp to the development of commonly used is the content of the line

CodePudding user response:

Not the standard used in c + + 11, it is ok to see,

CodePudding user response:

Personally feel that c + + to c + + 11 biggest ascension is the support of expression, direct completion the CPP no closure the shortcoming of the modern languages,
At this point, the CPP is very complete, the back of the new features, are the icing on the cake, with no feeling, don't worry about not to program,
So, I don't think it is of no use c + + 11, on the contrary, I think use very large

CodePudding user response:

Useful, many books are on the c + + 11, c + + 11 to learn is to learn c + +

CodePudding user response:

I'm too lazy to learn anyway, c + + 0 x what also don't want to see, use the book to teach before, generally will be enough, also with less than what advanced grammar, the basics, decentralization,
I think that c + + to do subtraction, remove some fancy, add some practical, less pit, rather than the more digging holes

CodePudding user response:

20 now, can not learn,, 11 well, currently with 11 is not much more special
