c99和c11之间的区别 [英] difference between c99 and c11

问题描述

我正在学习c。 这本书是基于C99的。我想在完成本书后将自己的知识更新为C11，或者如果存在重大差异，请更改资源。因此，我要的是一种解释或资源来更新我的知识。我只找到了此来源。但是，它似乎不包含我需要或不简洁的信息。

I am learning c, presently. The book I read is C99 based. I want to update my knowledge to C11 after finishing this book, or change resource if there is a major difference. Thus, what I ask is for is an explanation or resource to update my knowledge. I only found this source. Nevertheless, it does not seem to encompass the information I need or not concise.

预先感谢。
P.S：我想学习C11，因为我认为这是目前流行的标准。否则，请通知我。

Thanks in advance. P.S: I want to learn C11 since I think it is the prevalent standard now. If not, please inform me.

C11标准的良好概述：

Good overviews of C11 standard:

• https://en.wikipedia.org/wiki/ C11_（C_standard_revision）

• https://smartbear.com/blog/test-and-monitor/c11-a-new-c-standard-aiming-at-safer-programming/

该标准包括对C99语言和库规范的一些更改，例如：

The standard includes several changes to the C99 language and library specifications, such as:

• 对齐规范（ _Alignas 说明符， _Alignof 运算符， aligned_alloc 函数，< stdalign.h> 头文件）


• _Noreturn 函数说明符和< stdnoreturn.h> 头文件



• 使用 _Generic 关键字的类型通用表达式。例如，以下宏 cbrt（x）转换为 cbrtl（x）， cbrt （x）或 cbrtf（x），具体取决于 x 的类型：

• Alignment specification (_Alignas specifier, _Alignof operator, aligned_alloc function, <stdalign.h> header file)
• The _Noreturn function specifier and the <stdnoreturn.h> header file

• Type-generic expressions using the _Generic keyword. For example, the following macro cbrt(x) translates to cbrtl(x), cbrt(x) or cbrtf(x) depending on the type of x:

#define cbrt(x) _Generic((x), long double: cbrtl, \
                          default: cbrt, \
                          float: cbrtf)(x)

多线程支持（ _Thread_local 存储类说明符，< threads.h> 标头，包括线程创建/管理功能，互斥量，条件变量和线程特定的存储功能，以及 _Atomic 类型限定符和< stdatomic.h> 用于不间断对象访问）。

Multi-threading support (_Thread_local storage-class specifier, <threads.h> header including thread creation/management functions, mutex, condition variable and thread-specific storage functionality, as well as the _Atomic type qualifier and <stdatomic.h> for uninterruptible object access).
