Ah yes, the infamous discussion.
Ignore this thread if you wish, I just thought I'd post my thoughts which got me thinking on the topic.
6 letters and a number, 7 keys
A total of 14 characters for int main / return 0.
A total of 14 characters.
7 again - not returning anything ( small program )
8 again - not returning anything ( small program )
It actually isn't harder to say int main, it's equal when returning something, and easier when not. It's also safer.
Void main, is truly wrong.
