改 windows default boot 非常容易。在 Grub 用 single user

你是用普通用户 login 么？
先试试用 text mode 启动然后再 startx? |

qwerty优越，但是人们已经习惯了qwerty，所以dvorak键盘只能是小众……
作为 interactive shell 的很好用，作为script interpreter 有些特性也简化了程式
，但是因为不是default 因此大部分script还是不要用zsh特性来写，只能用bash甚至
sh。不过目前写script的主流本来也不是shell script language了。

发帖数: 618 | 7 Why does default exception use const char* instead of std::string
when defining the what() member function?
const char* const what() const;
I think the reason is to avoid dynamic memory allocation so no
additional exceptions are thrown, which might be caused by
the std::string class. |

发帖数: 9764 | 9 "You can provide default arguments for template parameters in class
templates, but not function templates."
the words are from "Thinking in C++" V2. The first part is easy understood,
which is something like this
template class Stack {...}
But how to understand the 2nd part, "not funtion templates". Is it something
like this, which should be illegal according to this rule?
template T sum(T* a) {...} |

发帖数: 372 | 10 The rule says you can have default *value* such as N=100 in template class,
but in template function you cannot do this. |

发帖数: 9764 | 11 My questionn is how to understand the "words" from the book. N=100 is about
the default parameter, but I don't think the "words" is talking about it. In
fact, you can not have (int N) as function template parameter.

confusing enough already. Their meanings even change over time!
Now back to OP's question. This is also a question for both thrust and
randomtiger: What is the value of "int()"?
My understanding is that this means a value-initialization (or default-
initialization in the old days), so its value is 0. Therefore, the
vector array must be initialized to 0's. This result actually has
nothing to do with the behavior of current def |

I don't want to switch the system language often since it requires reboot.
Is there any way to configure the Visual Studio defaulting to code page

发帖数: 421 | 25 大牛，同学们，请教，static member method 可不可用default argument?比如，
enum Index
{
INDEX_A = 0,
INDEX_B
};
class foo
{
public:
static void method1( int a, int b = Index::INDEX_A);
};
编译可以过，但有什么要注意的地方？
多谢！ |

发帖数: 3299 | 26 你用的是那个版本的IDE，我用的是Code::Blocks
int b=Index::INDEX_A 或int b=Index.INDEX_A无法通过编译
只能用 int b=INDEX_A 或 Index b=INDEX_A;
太落后了。
而且enum 在C++是个class么？INDEX_A 的default value 是0，INDEX_B是1. |
