What's the difference between main() and int main()?

Question

I'm familiar with int main() and void main(), but I saw that our professor at uni uses main () -just main(), nothing else- in his codes, what exactly does it do? I read that it won't work on new C standards, but I tried it on my computer and it worked fine.

Does main() return a value like int main() or is it more like void main()?

`void maion()` is not a valid signature for a hosted environment. And all of your examples are ancient and deprecated. If you don't have arguments, use `int main(void)`! — too honest for this site, Nov 21 '16 at 18:11

It used to be you could leave them off in C and that would default to int, but no more. As for the main function. The return type of main must be int.
