what type does appointment->GetDateTime() return?

it must be a std::string. what does your error messages say?
you should have a "callstack" of how it tried to resolve the tempalte in your output window in visual studio if your using it

[main fern]

I'm using clion by jetbrains. appointment->GetDateTime() returns a DateTime class object. The DateTime Class takes in two strings. I hope that answers you question.

The error message I'm getting is No matching member function for call to 'insert' So I believe that the issue is that trying to call the insert function incorrectly?

I'm not sure what callstack is. Is it a VS Code thing? I'm not too good with remembering all of the functions without looking at my notes or online.

your trying to insert a DateTime into a set that only takes std::string so there wouldnt be a function insert(DateTime)

[main fern]

Ok, I think I get it. So I need to turn it into string and then inset that into the set right?

[simple sinew]

can you not change the set to accept DateTime?

change std::set<std::string> to std::set<DateTime>

but if this is some sort of assignment of yours and you cant alter that then that would be a way to do it too yes

[main fern]

Unfortunately it says to " - Return type is a set of strings"

[simple sinew]

convert to a string it is

[main fern]

So should be the last question. Does the .push_back(), also need to be converted to a string?

//error No matching member function for call to 'push_back'
appointments.push_back(appointment);

I tried converting to a stringstream, but I got the same error.
appointments.push_back(ss.str());

[simple sinew]

what does the DateTime class look like?
does it have a function tostring or soomething like that?
are you meant to create one?

new classes you create dont have any implicit to string function, you have to do it yourself

It doesn't have a to string function, but is that what I'll need for the push_back function? It didn't work like the other methods.

[simple sinew]

it does, you have a GetDate and GetTime that returns the date and time as strings.
something like set.insert(dt.GetDate() + " " + dt.GetTime()) should work for you

[main fern]

ok thank you so much!
