Well, the subject is related to Chinese processing, so it requires C + + to read Chinese characters for processing.First use the wchar_t character, which is the wide character, and then define:1#include 2#include 3 4 using namespacestd;5 6 intMain ()

C + + keyword Static,register,const,volatile,extern Static variables are scoped to a file, space is allocated at the beginning of the program, Space is freed at the end, default is initialized to 0, and its value can be changed when used.
