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

Hi,

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

#include <iostream> #include

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

Hi In C++, you need to double your escape characters, so that in order to pass '.*\._[0-9]+' to the RE, you need to pass '.*\\._[0-9]+' to the compiler. With the string that you use, the compiler will strip the sole backslash, and the RE will get '.*._[0-9]+', which isn't what you want.
