int main().
void main() might not even work for all compilers.
It's also a standard for C, so there's really no point in getting into the habbit of making it void.
Void doesn't have return type, int does, also "void main" is used generally in Microsoft compilers, but as for ethics of programming "int main" is correct. But you can use whichever you like, but using "int main" you can return 0 to check your program at runtime for errors.
Good practicies: int main returns 0 which informs us that program ran successfully ^^ void main returns nothing so we cannot acknowledge if program had error during runtime or not (assuming the error log is off)
