Thread: 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

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; 
}
