在括号和单引号之间提取带单引号的字符串

I have the following code :

我有以下代码:

  #include <iostream>
#include <regex>

using namespace std;

int main()
{
  string s;

      s = "server ('m1.labs.terad  ata.com') username ('us er5') password('user)5') dbname ('def\ault')";

    regex re("(\'(.*?)\'\)");
    sregex_token_iterator i(s.begin(), s.end(), re, 1);
   sregex_token_iterator j;

    unsigned count = 0;
    while(i != j)
      {
        cout <<*i<< endl;
        count++;
        i++;
      }
    cout << "There were " << count << " tokens found." << endl;

  return 0;
}
