C++ error Expected primary expression before "'" token (using getline on an ifstream?) -

i getting many errors along lines of "error: expected primary-expression before ',' token" wherever using getline function in code. looked @ examples of people using getline on ifstreams, , thought maybe had put "std::" before calling function (not sure though?) didn't work either.

here's first bit of code; i'm assuming whatever error i'm making same throughout.

#include <stdio.h> #include <iostream> #include <fstream> #include <string> using namespace std;  struct listnode{   string user;   string salt;   string encrypted;   string password;   listnode* next; };   int main(){    /* initializes singly linked list hold user data */   listnode *root;   listnode *conductor;   root = new listnode;   conductor = root;    string temp;    //creates , opens filestream password file                                                                         ifstream psswdfile ("example.txt");    if(psswdfile.is_open()){     //we assume there @ least 1 line, , initialize head of                                                      //the list                                                                                                              std::getline(psswdfile&, (conductor->user)&, ':');     std::getline(psswdfile&, (conductor->salt)&, ':');     std::getline(psswdfile&, (conductor->encrypted)&); 

it looks have misunderstood way pass parameter references c++ functions. unlike pointers need obtain address using & operator, functions take references not need anything: pass assignable expression:

std::getline(psswdfile, conductor->user, ':'); 

the compiler has forward declaration of function, knows pass whatever passing reference.
