Hi,
the simple code is below:
____________________________________________________________________
#include <iostream>
#include <string>

#include "boost/regex.hpp"
using namespace boost;

regex expression("this is ([[:digit:]]*)");

int main(int argc, char* argv[])
{
        while (true)
        {
                char buf[1000];
                memset(buf, 0, 1000);

                std::cin.getline(buf, 1000);
                std::string str(buf);

                cmatch match;
                if (!regex_match(str, match, expression))
                {
                        std::cout<<"Don't match"<<std::endl;
                        continue;
                }

                for (int i = 0; i < match.size(); i++)
                {
                        std::string msg;
                        msg.assign(match[i].first, match[i].second);
                        std::cout<<msg<<std::endl;
                }
        }
        return 0;
}
____________________________________________________________________________________

the makefile is below
