What is wrong with this C code ?

[Indian]

HI,
I am trying to read come numbers from a text file and than convert those numbers to floats.Here is my code,Everything looks fine but still I am not able to understand that why it is giving segmentation fault:-

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#include<math.h>

main()
{
    FILE *fs;
    char ch,d;
    char str[20];

    fs=fopen("text","r"); //I am reading a file :)
    int i;

    while((ch=fgetc(fs))!=EOF)
    {
        i=0; // assigning index to 0
        
        if(ch!='\t' ||ch!='\n')
      {
            str[i]=ch;
            i++;
            while((ch=fgetc(fs))!='\t')
            {

                str[i]=ch;
                i++;
            }

            str[i]='\0';
            
            func(str);
            
        }
        else
            continue;
    }
    fclose(fs);}

func(char *str)
{

        float a;

        a=atof(str);

        printf("%f",a);

}

I hope the code is clear to all

regards

Hey, I *just* woke up and actually compiled your code. Thats gotta be worth somehting.

In bloodshed two other errors were the 'late' definiton of func and that it doesnt return at least void.
