Could you ask a specific question? What is the purpose of you're program?

[neoazores69]

I "finnish"'d it.

On-topic
Place your code in code tags and indent it properly, which makes your code a lot more readable. Although I've only heard a vague description, and still don't see how your approach would do anything.. I do see some things that are obviously wrong:
In escolherilha, you put ilha behind a comment line, so cin >> ilha; is an illegal action. Secondly, it doesn't make sense to use the comparisons like that; I believe you want this instead:

if (ilha == '0') ref = 0;
if (ilha == '1') ref = 1;
// etc. 

Edit:
Missed the ilha at the top. Yet, another point arises, why check every single value and set it to a new variable when it's already in a variable you aren't going to change?

int escolherilha(string msg) {
cout << msg << endl;
do {
cin >> ilha;
} while (ilha < 0 || ref > 8); // Should be <0 and not <1.
return ref;
}
