user defined function

hi guys,

I am facing an error called no function prototype.
can you guys please help me with that. my code is
#include "udf.h"
DEFINE_PROFILE(heatflux,thread,nv)
{
int p=110.111;
int i;
int h[6]={123800,3033966,6067932,788100,62205,45600};
float n[0];

int num=6;
face_t f;
begin_f_loop(f,thread);
{
F_CENTROID(n,f,thread);

for(i=1;i<num;i++);
{
F_PROFILE(f, thread, nv) = h(i) + ((h(i+1)-h(i))*(p-n(i)))/(n(i+1)-n(i));
}
/*return 1;*/
}
end_f_loop(f,thread);
}

I am trying to do piecewise linear approximation for heat flux variation along the length of the rocket nozzle.

Code:

DEFINE_PROFILE(heatflux,thread,nv)

{

real p=110.111;

int i;

real h[]={123800,3033966,6067932,788100,62205,45600};

real n[]={123800,3033966,6067932,788100,62205,45600};

int num=6;

face_t f;

begin_f_loop(f,thread);

        {

                F_CENTROID(n,f,thread); 

                for(i=1;i<num;i++);

                {

                        F_PROFILE(f, thread, nv) = h[i] + ((h[i+1]-h[i])*(p-n[i]))/(n[i+1]-n[i]);

                }

        }

end_f_loop(f,thread);

}

best regards

Thank you @Alexanderz
