Bool operator usessss

#1

why in the class bool operator() (person a, person b){}

what is the difference between that and bool operator(person a, person b){}

And what is the difference between that and bool (person a, person b){}

#2

bool operator() (person a, person b) {} basically overloads the operator () and calls this functions.
You cannot have bool operator(person a, person b){} because operator is a keyword so you cannot use it as a function name. If you had any other name like bool Operator(person a, person b){} then this function would get called by calling “classname.Operator()” but the “overloaded” function gets called by the use of ()
