Binary XML has aroused a lot of discussion. One reason is that relatively compact transmission formats are needed, especially for Web Services. The existing ready-to-use solution is compression. This tip illustrates how to use compression to prepare XML files for transmission in Web Services.In the discussion of XML, the view of binary XML has always been heard. Due to its traditional text and the rules required to make international texts more friendly, XML is very lengthy. The equivalent binar

virtual function of the subclass is called through the constructor of the parent class, and this virtual function may fail to access data members of the subclass. Let's take a look at the compiled code generated by vc7.1 to easily understand this behavior.

constant Stack (Stack Space ). Why does tail recursion achieve constant stack space? We use the famous fibonacci series as an example to illustrate this. The implementation method of the fibonacci series is generally like this. int FibonacciRecur (int n) {if (0 = n) return 0; if (1 = n) return 1; return FibonacciRecur (n-1) + FibonacciRecur (n-2);} but note that this implementation method is not tail recursion, because the last action of tail recursion must be called itself, the final action he
