“对于每个”微软具体？ [英] Is "for each" Microsoft specific?

问题描述

Visual C ++ 2010接受：

Visual C++ 2010 accepts:

std::vector<int> v;
v.push_back(1);
v.push_back(2);
v.push_back(3);
for each (auto i in v)
    std::cout << i << std::endl;

这是C ++ 11功能还是Microsoft扩展？根据维基百科，C ++ 11的for-each循环语法不同：

Is this a C++11 feature or a Microsoft extension? According to Wikipedia, the syntax of C++11's for-each loop different:

int myint[] = {1,2,3,4,5};
for (int& i: myint)
{
    std::cout << i;
}

推荐答案

包括每个（auto i in v）语法，只有为（auto i：myints） ，它只是一个扩展名。

The current standard draft does not include the for each ( auto i in v ) syntax, only the for ( auto i : myints ), so yes, it is just an extension.
