Answer 1

void main is no longer supportable in c /cpp you can use int main with return 0 or return EXIT_SUCCESS

Answer 2

hi Abhay
not an error, it's just a warning, and you can run out of it by adding: #pragma GCC diagnostic ignored "-Wmain"
this allows you to selectively enable or disable certain types of diagnostics, *or* simply you can just change the return type of the main function to int instead of void just like Raghuvanshi said..
