#include <stdio.h>

#include <math.h>

int main()
{
  FILE *infile;
  float skatertime[32][1500];
  int i, a, b;
  float left, right, add;

  infile = fopen("speed", "r");
  if (infile == NULL)
    {
      printf("speed not working\n");
      exit(1);
    }

  for (i = 0; i < 12; i++)
    {
      fscanf(infile, "%f %f", &skatertime[a], &skatertime[b]);
      printf("Left: %f	Right %f\n", skatertime[a], skatertime[b]);
      a++;
      b++;
    }

  return 0;
}

i keep getting these errors

can u tell me in the speed file what content you are having

[Adak]

In this line of code:

fscanf(infile, "%f %f", &skatertime[a], &skatertime[b]);

You need to specify the second index. Without it, you have an address to an array of 1500 elements.

Before the for loop starts, you want to initialize a and b.

If you faced that warning in only compile time it is not a problem with the content of speed file.
I think you faced in the compile time only. So it is a problem with your gcc.

I am working this program in Linux environment I didn't faced any problem.

If you are not declared a a and b variable also it will take some garbage value and it will process based on that. you can try with new installed gcc compiler. If you faced same problem inform again.
