1, Jackson Frame: This framework provides jsongenerator, objectmapper two classes provide a way to convert a Java object into a JSON object, JSON array format, or a JSON object, The array format is converted to a Java object. 2, Json-lib framework can also be used in JSON format and the conversion between Java objects, Json-lib provides the main classes are: Jsonobject, Jsonarray .... 3, show the use of two frameworks for mutual transformation: First, Json-lib:package Com.inspur.json;Import java

get the length of the S string, you should use sizeof (S. c_str (), because the string member function c_str () returns the first address of the string. In fact, the string class provides its own member functions to obtain the capacity and length of the string, namely capacity () and length (). String encapsulates string operations, so it is best to use string to replace C-type strings during C ++ development. 8. view the CPU peer bounds from the sizeof problem of union Consider the following:
