Pass An Array to a Pointer Function in C

#include <stdio.h>
#include <math.h>
double sum(double *x, int N) {
    int i ;
    double total= 0;
     for (i = 0 ; i < N; i++) {
         total += x[i];
     }
    return total;
   
}


int main()
{
  double (*stat)(double * , int);
  stat = sum;

  double a[] = {1, 2, 3};
  double Sum;

  Sum = stat(a, 3);

    printf("sum = %f ", Sum);

    return 0;
}
