C++11: Regex

Regular Expressions (Regex) were added to C++11. Here is an example:

#include <iostream>
#include <regex>
#include <string>

int main()
{
  std::string myString("abcdefg");
  std::regex  myRegex ("cde"    );
  std::smatch myMatches;

  std::regex_search(myString, myMatches, myRegex);

  if (myMatches.size() > 0) std::cout << myMatches[0] << std::endl;
  
  return 0;
}
// Output: cde
