Here are some class and method prototypes, labeled ONE, TWO, THREE and FOUR which are involved in four operator overloading, two as member operators, two as non-members: class classa { public: string operator+(classA other ); int operator+(int num); // method ONE // method TWO }; string operator+(classA firsta, string secondString); string operator+(string firstString, classA seconda); // method THREE // method FOUR (Assume no other operators are defined which involve this class.) Match each of the client (main() operator invocations to the method that it calls, or choose ILLEGAL/NOT SHOWN if it is illegal or it is legal but attempts to call an operator which is not defined above. Variable names firstA and secondA are also assumed to be defined in main() as objects of classA: METHOD TWO [Choose ] ILLEGAL/NOT SHOWN [ Choose ] METHOD ONE [Choose ] METHOD THREE [Choose ] METHOD FOUR [Choose] Here are some class and method prototypes, labeled ONE, TWO, THREE and FOUR which are involved in four operator overloading, two as member operators, two as non-members: class classa { public: string operator+(classA other ); int operator+(int num); // method ONE // method TWO }; string operator+(classA firsta, string secondString); string operator+(string firstString, classA seconda); // method THREE // method FOUR (Assume no other operators are defined which involve this class.)
