Why is

    //return void
}

bad?

The other day I typed this and someone pointed out to me that it is wrong to do so. I was so confused. I have been writing like this for a while now, I know it isn't C++ standard, but the compiler doesn't give out any warnings. Why is this wrong?

Answer 1

Because the compiler you use does not error out on it, it doesn't mean other compilers won't. You know its not standard, after all...

Answer 2

It is wrong exactly because it is not standard. One compiler might accept this, another might complain, and the pedantic believers will burn your ass on the stake anyways.
