[Boost-users] [Regex] : Unknown character sequence.

Hi,

   I'm new to regex.  This is basically what I was trying.

#include <iostream>
#include <boost/regex.hpp>

int main()
{
    std::string input = "sand._12";
   boost::regex reg(".*\._[0-9]+");

   ......
}

I get a warning which says "Unknown escape sequence '\.' .  Its the same
case with any other special character or even '\s' .

I guess I'm missing something very simple.

Any ideas ?

Thanks in advance.
