Is there any standard for returning values from a function?

Hi, Is there any standard for return values from a function, for example if my function returns only two value(true/false) then i would like to assign bool as its return value, but if i have got three values(0,1,2), then what data type should be the used as return value.

you have plenty of types. if the function may return little integers, char is good enough. but short, int, long are possible choices.

If the function may return only a small set of integers (such as {0,1,2}) then the enum type is a good choiche. Usually you can assign to each member of the set a meanigful name:

enum TrustLevel
{
LOW = 0,
AVERAGE,
HIGH
};
