Sometimes, you want the C ++ function to return multiple irrelevant values. Before introducing STL, the method to achieve this goal is to create the structures of all irrelevant variables, and return them in the form of pointers or references or pass them to the function as parameters -- but none of them are the methods intended by the table

Method 1: generate an xml file through StringBuider (the thread is not secure and does not need to be locked through detection, which is highly efficient. It is recommended to use a single thread. StrigBuffer thread security, low efficiency, and multi-threaded environment ).
As follows:
Method 2: generate an XML file using the XML sequencer. null in the Code is the namespace. Ta
garbage collection? for gc, when a programmer creates an object, the GC starts to monitor the address, size, and usage of the Object. typically, a GC uses a graph to record and manage all objects in the HEAP. In this way, you determine which objects are "accessible" and which objects are "unreachable." When the GC determines that some objects are unreachable, it is the responsibility of the GC to reclaim those memory Spaces. OK. RideThe sequencer can
Questions about the PHP development project design Documentation
Hello everyone! I am using PHP to make a Web site, but I do not know how to write PHP design documents, because there are no classes, all functions, and the project design of the Java EE is not the same, do not know how to write. Which shrimp guide little brother, greatly appreciated!!

Today even look at three papers, not very detailed to see, nor concrete to achieve, but probably understand some new ideas. These three papers, an overview of the Decoder-encoder model, an extension of the model, the first proposed attention mechanism, the last one elaborated the LSTM and GRU work mechanism.

If a single for loops, it's not a big deal, but the burden is heavy in the face of a huge code base full of loops, especially nested loops.
