Linux C + + Copy file issues

Automatically include sub-directories;
Complete <[source path via command line parameters] Source file >< Destination path >
The source file name is required to support the wildcard character ' * ', for example: *.zip or *.rar, support the above two formats;

#include <string.h>
#include <io.h>
#include <stdio.h>
