what is this dot?

[k99]

example = str.emphatic();

what is this .?
is this a assigning function prototypes?
base on the = (assigning operator)
and emphatic(); (prototypes function)

Please help me understand

[MiiNiPaa]

. is a member selection operator.
This means that whatever class str is an instance of, has member function emphatic

In your snipped example is assigned result of calling emphatic() member function on str object
