Hello I'm having problems using fscanf. I'm using it to read data from a file into an array and for short files it works fine i.e. with about 12 bits of data but now I have a file with say 200 bits of data and this just causes the program to crash does anyone know what I'm doing wrong please. I've included a copy of the program below followed by the data from one of the long files I'm trying to read.
Code:
#include <stdio.h>
#include <math.h>
char file[10];
FILE *data;
int main ()
{
{
do
{
printf ("Type in the name of the data file: ");
scanf ("%s", &file);
//Open file
data = fopen(file, "r");
if (data == NULL)
printf("\n ERROR - Cannot open the designated file \n") ;
}
while (data==NULL);
}
int count;
int count1;
float a[count];
count=0;
while(!feof(data)) {
fscanf(data,"%f", &a[count]);
count++;}
// Test to print values from file
for(count1=0; count1<count-1; count1++)
printf("Is = %f\n", a[count1]);
}
File
