Is it possible that enum variables can take a value which is out of set ?

Hi,
Is it valid to assign a value which is out of the set to an ENUM variable ?

for example
-------------
enum status
{
installed = 10;
uninstalled = 20;
repair = 30;
};

enum status current_status;
current_status = 10;
if(current_status == installed)
current_status++;

Can i write a code like this ?, here if the 'if' condition satisfies, the value of current_status will be set to 11 which is out of the set, is it going to be any error in this case.

Thanks
Kiran

An enum is just an int with a few compiler restrictions.

The compiler may complain, but if you convince it to do as you say, you won't have any runtime problems resulting.
