Thread: Question about int and void main()

I just bought the new edition of Let Us C by Y.P. Kanetkar (8th edition). In the examples so far the book has used:

Code:

void main() {}

When I compile, it gives an error, it should be int not void. I have had the same results using Code::Blocks and terminal on Mac to compile. So why would the book use void?

It's a common misconception usually.
However, it is correct to use int main.
The standard says that main must return int. Returning void or anything else from main is non-standard and also therefore undefined.

Should answer your question.

If the book goes onto use gets(buffer) or fflush(stdin) then throw it in the shredder or take it back to the store and get your money back. It will be utterly useless to you, and just a cheap piece of fiction for everyone else.
