This is the part of the code that gets the error:

rational rational::add(const rational q) const
{int d1=q.get_denominator();
int denom= denominator;
int f=greatest_common_divisor(denom,d1);
int g=q.get_denominator()/f;
int h=denom/f;
int n=g*numerator + h*q.get_numerator();
int d=g*denom;
rational r(n,d);
r.lowest_terms();
return r;}

when it passes an argument through "greatest common divisor" during compiling, I get the error in the add function:

int rational::greatest_common_divisor(int a ,int b)

{ if(b<0)
{b=-b;}
if(a<0)
{a=-a;}
if(a==0)
{return(b);}
else
if(b==0)
{return(a);}
// a = b*q + r
int q, r;
q = a/b;
r = a%b;
return greatest_common_divisor(b,r);}

Any help would be great. Thanks!

I greatly advise proper formatting if you want help.
