I need to print the values of 'ff' in the following program, how can i do it:

#include <stdlib.h>
#include <math.h>

#define fmin 1
#define fmax 100
#define DeltaF 1
#define NumSeg 100
#define NumFre 50
#define dF 1

float Normal_Distribution_Random(double mean, double stand_val);

main()
{

double func_val[3];
double fnm[NumFre][NumSeg];
double fmean[NumSeg];
double x1, x2;
double ff;
double Rjnm[3][NumFre][NumSeg];
int ii, j, k;
fmean[0]=fmin;
for (ii=1; ii<NumSeg; ii++)
{
fmean[ii]=fmean[ii-1]+dF;
}
for (j=0; j<NumSeg; j++)
{
for (k=0; k<NumFre; k++)
{
Normal_Distribution_Random(fmean[j], DeltaF);
fnm[k][j]=ff;
}
}
for (ii=0; ii<3; ii++)
{
for (j=0; j<NumSeg; j++)
{
for (k=0; k<NumFre; k++)
{
Normal_Distribution_Random(0, 1);
Rjnm[ii][k][j]=ff;
}
}
}
}



float Normal_Distribution_Random(double mean, double stand_val)
{
double u1, u2, w, mult,call,ff;
int flag;
double x1,x2;
flag=1;
w=0;
if (call==1)
{
call=!call;
ff=mean+stand_val*x2;
}
else
{
while (flag==1)
{
u1=-1+((double)rand()/RAND_MAX)*2;
u2=-1+((double)rand()/RAND_MAX)*2;
w=pow(u1, 2)+pow(u2, 2);
if (w>0 && w<1)
{
flag=0;
}
}
mult=sqrt((-2*log(w))/w);
x1=u1*mult;
x2=u2*mult;
call=!call;
ff=mean+stand_val*x1;
}
return(ff);

}
