Isn't void main() mot allowed in C++ ??

I am C++ learner, i don't know about IoT. Just out of curiosity, Isn't void main() considered invalid from C++ 98.Or is it only for normal C++ and not the C++ IoT devices use ???
Edit: I am talking about IoT generally, bcoz I have come across some using void main() , Because its a IoT repo. Perphaps you can guide me. Thanks

void main() is definitely not standard C++. If your compiler supports it then you still shouldn't use it as it could have undefined behavior.

For IoT a lot of the time this a moot point as the frameworks handle this for you. For example, with Arduino, your main function (as in the first part of your code that is called) is setup, called by the Arduino framework.
