“non-standard syntax; use '&' to create a pointer to member” error in Visual Studio 2015

Question

I have this function:

std::string Room::getUsersAsString(std::vector usersList, User * excludeUser)
{
    std::string usersNames = " ";         


        

Answer 1

You are missing the function call parentheses in these lines:

if (usersList[i]->getUsername() != excludeUser->getUsername) {

and

usersNames.append(usersList[i]->getUsername);

Try changing them into this:

if (usersList[i]->getUsername() != excludeUser->getUsername()) {

and

usersNames.append(usersList[i]->getUsername());
