its from a book im reading but it dont work, i cannot fix it lol.

any ideas, the errors are below the code.

Code:

please help. cheers in advance. reece.

1) It's int main(), not void main().
2) You have enum constants of the same name as some functions. They conflict.
3) The definition of ~Rectangle is missing the braces.
4) You need to declare functions before using them. (DoMenu() error on line 65)
5) (Line 134) Missing argument list: exactly what the error message says.

cheers mate it worked.
shame the program was pretty useless lmao.

it says void main in the book. so some compilers accept it?

Some crazy compilers might, but we like code that all compilers like. That code is

Code:

---

int main() {}

*drools*

Yes, but it is nonetheless non-standard.
