Newbie to C Language... I've been core dumped

[Handyman]

Hello everybody, I'm a programming newbie that needs some help. I'm working on an assignment for my C Language class and have the following code:

/*
 *  COP 3223
 *  Summer C 2002
 *  Call by Reference in a C Program
 *  June 24, 2002
 */

#include <stdio.h>

void read5(double *, double *, double *, double *, double *);

int main(void) {

  double u, v, w, x, y;

  read5(&u, &v, &w, &x, &y);

  printf("%f%f%f%f%f", u, v, w, x, y);

  return 0;

}

void read5(double *i, double *j, double *k, double *l, double *m) {

  double temp1, temp2, temp3, temp4, temp5;

  scanf("%lf%lf%lf%lf%lf", temp1, temp2, temp3, temp4, temp5);

  *i = temp1;
  *j = temp2;
  *k = temp3;
  *l = temp4;
  *m = temp5;

}

I'm trying to write a function that takes five arguements of type pointer to double and reads 5 values from the key board. But when I try to compile this thingy I get core dumped after entering my five numbers. What the heffer did I do wrong? It looks good but works bad

Any tips and hints to what I'm doing would be helpful, not trying to get you guys to do my homework, but I've been at this for a few hours and can't get this 'should be easy' function to work

Thanks in advance
