c++ - Print .pdf filenames from a directory with Boost.regex -

-

this code:

path path = "e:\\documents\\"; boost::regex reg("(*.pdf)"); for(recursive_directory_iterator it(path); != recursive_directory_iterator(); ++it) {     if(boost::regex_search(it->string(), reg))     {         cout << *it << endl;     } }

but , abort() error in visual studio, after running program, problem in line:

boost::regex reg("(*.pdf)");

am not declaring regex object ?

*.pdf isn't regex, it's glob (for file matching). need

boost::regex reg("(.*\\.pdf)");
  • .: matches 1 character
  • *: 0 or more of previous match
  • \\: make single \ escaping (ignore regex meaning of next character)
