Answer 1

you have extra } before main. try to make your code a bit tidy next time by using indentation/tab. so you can spot this kind of error more easily

ex.

return "World";

Please arrange your code to easely see your errors. Use indentation first of all. Do not use copy paste because you will make the same mistake and you will not notice it
