Smart pointer and smart pointer Unlike Java and C #, C ++ does not have a garbage collection mechanism, but it provides a powerful and flexible management mechanism that allows developers to avoid memory leaks. You can use new to obtain the memory or create objects, and delete must be used to release them, so as to avoid Memory leakage. At the same time, the allocation and usage can be encapsulated with classes to ensure no memory leakage. # Include Using namespace std; # Include # Include

For a long time did not do XML aspects of parsing, today received a small task, need to parse the XML inside the field content, incidentally reviewed the XPath knowledge. The XML that needs parsing is the kind of document to be namespace, and at the beginning of the parsing, I feel that it is the name space that has dealt with the problem before, but the time is long, forgotten, and not recorded.Toss it for a while and finally find a way.

Everyone generally said that the camera card, whether it is CF card, SD card, XD card, etc., in fact, belong to the data memory card. Because the default built-in space for a typical digital camera is 1-2g, there is no way to store large numbers of digital photos, so most cameras have slots available to add additional memory cards. Because of the accidental deletion, formatting, memory card read failure, the camera memory card data belongs to one of t
