Help reading data file...

I can't get the program to read the data file. I am supposed to output the five values in the data file five per line using pointers. When I debug it is not reading any of the values in the data file.
Any tips? Thanks!
Here's my program:


#include <stdio.h>
FILE *myinptr;
void fiveperline(double *);
int main()
{
int i;
double x[10];
myinptr=fopen("data.txt", "r");
for (i=0;i<10;i++)
fscanf(myinptr,"%.2lf", &x[i]);
fclose(myinptr);
fiveperline(x);
return 0;
}


void fiveperline(double *x)
{
int i;
for (i=0;i<10;i++){
printf("%.2f\t", x[i]);
if((i+1)%5==0)
printf("\n");
}

}

Data File (data.txt)
8.50
8.60
8.90
7.95
8.89
6.95
7.25
8.76
9.45
8.25

Change this
fscanf(myinptr,"%.2lf", &x[i]);

To this
fscanf(myinptr,"%lf", &x[i]);

Seems to work then

I forgot to log in when I posted the topic. It's working. Thanks!

edit:got it to work, but how would I send it he mean value back to the main using a pointer and not a return statement? THanks!

#include <stdio.h>
FILE *myinptr;
void fiveperline();
void mean(double *);
void main()
{
int i;
double x[10];
myinptr=fopen("data.txt", "r");
for (i=0;i<10;i++)
fscanf(myinptr,"%lf", &x[i]);
fclose(myinptr);
fiveperline();
mean(x);
}

void mean(double *myinptr)
{
int k;
double mean=0;

for (k=0;k<10;k++){
mean+=*(myinptr+k);
}
mean=mean/10;
printf("mean=%.2lf", mean);
}

Does no one read anymore?

Code:

---

#include <stdio.h>
FILE *myinptr;
void fiveperline();
void mean(double *);
int main() // YES, int
{
int i;
double x[10];
double meanval;
myinptr=fopen("data.txt", "r");
for (i=0;i<10;i++)
fscanf(myinptr,"%lf", &x[i]);
fclose(myinptr);
fiveperline();
mean(x,&meanval);
printf("mean=%.2lf", meanval);
}

void mean(double *myinptr, double *meanptr)
{
int k;
double mean=0;

for (k=0;k<10;k++){
mean+=*(myinptr+k);
}
  *meanptr=mean/10;
}
