In Ruby, how do I skip a loop in a .each loop, similar to 'continue' [duplicate]
...from within a block intentionally can be confusing. For instance:
def my_fun
[1, 2, 3].map do |e|
return "Hello." if e == 2
e
end
end
my_fun will result in "Hello.", not [1, "Hello.", 2], because the return keyword pertains to the outer def, not the inner block.

纯虚函数例如 void fun() = 0; 是纯虚函数,不是纯虚函数不作要求。
另外,void fun() { } 空函数体也是实现。
纯虚函数相当于C#中abstract抽象类。

std::function and std::bind: what are they, and when should they be used?
I know what functors are and when to use them with std algorithms, but I haven't understood what Stroustrup says about them in the C++11 FAQ .

Why is it wrong to use std::auto_ptr with standard containers?
...se of move semantics (its specification requires rvalue references), so it fundamentally requires C++11. However (and related) the C++11 Standard no longer says that an STL element type must be "copy-constructible" and "assignable"; being move-constructible and move-assignable suffices. Indeed uniqu...
C# using streams
...sfer the strings to and from the stream as bytes. So
myStreamWriter.Write(123);
will write "123" (three characters '1', '2' then '3') to the stream. If you're dealing with text files (e.g. html), StreamReader and StreamWriter are the classes you would use.
Whereas
myBinaryWriter.Write(123);
