errors, help
This is the part of the program that is giving me problems, and I don't know
why. I get the same error for each line, which is basically the same. Everything
is declared, and as far as I know, i'm useing the right syntax.
/**Test to display numerators and denominators*/
int testNum1 = r1.numerator();
int testNum2 = r2.numerator();
int testNum3 = r3.numerator();
int testNum4 = r4.numerator();
int testNum5 = r5.numerator();
int testNum6 = r6.numerator();
int testDen1 = r1.denominator(); // Ok, this is the same thing as
the numerator code above, but this code does not give me any errors.
int testDen2 = r2.denominator();
int testDen3 = r3.denominator();
int testDen4 = r4.denominator();
this goes on…..
//These are the errors that I ‘m getting. Please help.

Re: errors, help
That means that r1 and the rest are objects of class Rational, which you may
have written yourself or got from somewhere else. It has a method called
numerator that takes a single Rational parameter, but it does not have a
method called numerator with no parameters. That's what those messages are
saying. But it **does** have a method called denominator with no
parameters.
If Rational is what I think it is, then its numerator method is misdeclared
and should not have any parameters.
