PASSING ENUM TO A FUNCTION

[villica]

How do you pass an enum to another function. The enum is in the header file under the public section. Any ideas anyone. Thank YOu <p>Villica<br><a href=mailto:villica67@hotmail.com>villica67@hotmail.com</a><br><a href= > </a><br>

I am uncertain, how exactly you have it setup, but because I havent worked with much enum, but it might work similar to most other things like a struct or someting that cant just simply pass its values like a charater arary without using pointers.<br>
<br>
I might try somehting like passing by reference<br>
void something(enum &theenum) <br>
or might need to be like a struct, which is more of a class than an object<br>
(enum Enumname &objectname)<br>
this would pass by reference, it doesnt make a copy, so any changes you make if you decide to will affect the original copy, I would have to try this to be certain you can pass it, now if it's declared in a class <br>
something like (enum classname::enumname &object) might be required, which only works if the function knows that class.<br>
<br>
let me know what happens <p>Karl<br><a href=mailto:kb244@bellsouth.net>kb244@bellsouth.net</a><br><a href=

In C++ the constants in an enum are local to a class and known only to member and friend functions of the class. So if a class declares an enum , functions outside the class can refer to the enumerated constants by explicitly qualifying the name using the scope resolution operator. .<br>
For eg, <br>
Class finite {<br>
enum state{ init, reset, end};<br>
...<br>
}<br>
Now you can use the notation finite::init to access this constant. <br>
So you can just pass this to any function which takes integer as the parameter.<br>
Does it answer your question ?<br>
