How to search for a regular expression in c++?

Question

I'm working on C++,

I need to search for a given regular expression in given string. Please provide me the pointer to do it. I tried to use boost::regex library.

Following is the regular expression: regular expression to search : "get*"

And above expression i have to search in following different strings: e.g.

1.    "com::sun::star:getMethodName"
2.    "com:sun:star::SetStatus"
3.    "com::sun::star::getMessage"

so i above case i should get true for first string false for second and again true for third one. Thanks in advance.

boost::regex re("get.+");

example.

#include <iostream>
#include <string>
#include <boost/regex.hpp>
#include <vector>
#include <algorithm>

int main()
{
   std::vector<std::string> vec = 
   {
      "com::sun::star:getMethodName",
      "com:sun:star::SetStatus",
      "com::sun::star::getMessage"
   };
   boost::regex re("get.+");
   std::for_each(vec.begin(), vec.end(), [&re](const std::string& s)
   {
      boost::smatch match;
      if (boost::regex_search(s, match, re))
      {
         std::cout << "Matched" << std::endl;
         std::cout << match << std::endl;
      }
   });
}
