Her initial response was:

"You might not 'need' the return value right now, nonetheless void main() is not correct C++ according to the standard."

Answer 2

int main means at the end of main it should return a integer value, so at last line in main function we write return 0

Void main means at end of main, it should not return any value, so we don't use return. We cab use getch(); for void main
