具有“在类成员初始化”特性制作成C ++ 11？ [英] Has "In class member initialization" feature made into C++11?

问题描述

在课程初始化功能中，允许在类本身内初始化普通成员，

In class initialization feature, which allows to initialize normal members inside the class itself,

struct A {
  int a = 0; // error: ISO C++ forbids in-class initialization of non-const static member ‘a’
};

这是最新编译器gcc-4.6的错误（ -std = c ++ 0x ）。在C ++ 11标准或gcc中的此功能是否仍然不支持它？

This is giving error in latest compiler gcc-4.6 (with -std=c++0x). Has this feature made into the C++11 standard or gcc still doesn't support it ?

推荐答案

在C ++ 0x。在N3290§12.6.2/ 8有一个例子：

Yes, that is legal in C++0x. There is an example of this at N3290 §12.6.2/8:

struct C {
    /* ... */
    int j = 5; // OK: j has the value 5
};
