why this code does not generate an error message

[adlene80]

the method definition

-(Fraction *) add:(Fraction *) f
{
    Fraction *result =[[Fraction alloc]init];
    result.numerator = numerator * f.denominator +
    denominator * f.numerator;
    result.denominator = denominator * f.denominator;
    [result reduce];
    return result;
}
----------------------------------------------------------------------

the main routine
int main (int argc, const char * argv[])
{

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    Fraction * aFraction = [[Fraction alloc]init];
    Fraction * bFraction = [[Fraction alloc]init];
    Fraction * MyResult;

    // set fraction to 1/3
    [aFraction setTo:1 over:4];
    [aFraction print];
    NSLog(@"+");
    [bFraction setTo:1 over:2];
    [bFraction print];
    NSLog(@"=");
    MyResult = [aFraction add:bFraction];
    [MyResult print];
    [aFraction release];
    [bFraction release];
    [MyResult release];

Can you clarify your question?
