objective C question

Alright this will most likely aptly display my lack of programming prowess but I am trying to teach myself objective c and I am programming a simple fraction program. I keep getting this as the output! Can anybody tell me why or what I can do to fi it?

-(void) setDenominator:(int)d
{
denominator =d;
}

-(int) numerator
{
return numerator;
}

-(int) denominator
{
return denominator;
}

@end

//----Program section----

int main (int argc, char *argv[])
{
@autoreleasepool {
Fraction *myFraction = [[Fraction alloc] init];

[myFraction setNumerator: 1];
[myFraction setDenominator: 3];

NSLog (@"The value of myFraction is: %i/%i", [myFraction numerator], [myFraction denominator]);

}
return 0;
}


output:(lldb)

What does this mean? No errors and this lldb thing. Is it a setting or an error?
