[solved] Why this error?

Question

I used return type of main() as void but in code playground it gives an error saying main() should return int.
But if I do same thing in 'C' there is no error
Is it ide dependent or what????

Answer 1

By the standard, `main` must be declared as one of

int main()

or

int main(int argc, char *argv[])

or equivalent.

So, `void main()` is not standard C or C++. In C++ it is just plain illegal, and C allows "other implementation-defined" ways of declaring `main`. Some C compilers support `void main()` and some don't.

Long story short: Use `int`, everything else is illegal/nonstandard. It is shorter to write too so there is no reason not to.
