c++ - Error C3867 'DataBase::isUserAndPassMatch': non-standard syntax; use '&' to create a pointer to membe -

ive been trying figure out while couldent find solution.

when write code line in cpp file:

if(database::isuserandpassmatch(u->getusername(), " ")){} 

i error c3867. tried switch u->getusername() empty string (" ") still same error. tried this:

 if(&database::isuserandpassmatch(u->getusername(), " ")){} 

isuserandpassmatch:

bool database::isuserandpassmatch(std::string username, std::string password){} 

suppose have class definition:

class database { public    bool isuserandpassmatch() {return true;} }; 

if want call isuserandpassmatch member function, have have object:

database db; if( db.isuserandpassmatch() ) { } 

try it.
