0

I don't know the role of the return 0 in the program because whether i add it or omit it there is no deference in exuction of the program.

I try to swap the 0 by 1 the terminal indicate to something wrong.

    I wish the C99 spec hadn't licensed falling off the end of main, it confuses people out of all proportion to the time saved. – zwol Jan 29 '23 at 01:02
